I'm still learning fusion I imported the model from turbocad but I'm comfortable enough now to make every part in this just not assemble it yet lol once I crack the assembly I'll have a proper look at rendering.

I have the autodesk getting started pdf's including section on rendering can't find the link I got it from now but PM us you email and I'll email it you.

6 meg so won't let me upload here.

I have 5 years+ experience in turbocad which has helped take the edge off the learning curve but it's still a curve lol.

Personally couldn't get on with the videos but with a dual monitor setup would be ok, I downloaded the pdf onto tablet so I could have 2 screens. I found PDF's easier though and the PDF's are just written versions of the video tutorials.

I do have a 2nd monitor but it's going in the arcade table but I might borrow it temporarily ;) I ordered a few tutorials to be getting on with mostly to do with component assemblies, sculpting, simulation & making models for injection molding. So will need to a decent solution to learn from videos.

Be nice to do high quality renders but for what I do the renders would be more for me, like a lot of you renders look nice but the CNC machine doesn't give a shit about that lol.

---

I haven't looked at the CAM yet I wanted to get to about the same standard in Fusion as I was in Turbocad first so I'm comfortable editing models but interesting to read ;)

I think TBF on turbocad this is a properly set up render

Attachment 22891

I think it's pretty bloody good for a cad render.


e2a fusion can create some nice shots with little effort

Attachment 22892

Finally got it on my big dug benchs, almost like they were made for the router ;)

I'm going to have 1 continuous piece of ply under the router and MDF as the bed inside the frame on the supports.

I need the continuous piece for the vac bed, it will be slightly framed out so I can suck evenly across the bed.

Attachment 22910

Just need to cut a piece of chipboard for a shelf and I can start wiring up finally but not going to have much time till next week.

Are those benches from rapid racking lol

Big Dug benches, I've had them years so long I forgot I had them lol, they're rated for 400kg's each shelf so not worried there but these would be an expensive way to get bench for the machine if I had to buy them new.

I bought only the metal frame and bought the ply locally which was a lot cheaper than buying the kits but it still cost me £110 for both of them I could frame it out with extrusion cheaper than that but I have the benches so will use them for now.

At some point though I want the benches back so will need to source a more permanent solution.

My only concern with those benches is that they will take the weight fine, but once that gantry starts moving about, there's a lot of force trying to move the benchtop in the opposite direction. I have similar Big Dug racking, which is fine once bolted to the wall in a few places, and my old router sat on a similar bench. Might need a bit of diagonal bracing to resist the movement?

These are going to be a temporary measure but I can bolt them to the wall pretty easy if I move them to a different place in the unit.

I was going to sit the router on a sheet if ply which I'll drill into the bench tops as well. I need this sheet for my vac bed, clamps will make me want to murder someone lol.

Diagonal bracing hmmm, if they end up being used longer than I want I will consider it, but I would like to recover the benches for drill press and work areas and getting a cnc is only the start of the puzzle lol.

My Titan drill press is not what you would call professional lol.

Attachment 23020

Had a bit of time today so thought I'd start on the wiring but realised I'm missing 2 of the power input connectors on the stepper drivers, does anyone know what they are called?

Not going to try and cram the transformer in after all would be tight in the case and I would worry about heat, got loads of space under the router more than enough for everything.

Nice once Clive ;) but I don't want to wait that long just trying to ID them from Rapid online catalogue.

Hoping I can get them by Saturday so I can finish the wiring over the weekend have been busy last couple of weeks and she's so close to cutting now.


The drivers have 3 plug in sockets, 2 of my drivers are missing all the plugs, 1 of my drivers has 2 6 pin plugs but missing the 2 pin, the last driver has all 3 plugs.

e2a
I think this is one set of 6 (P1)
https://www.rapidonline.com/truconne...3-81mm-21-3094

Pretty sure the 2 pin plug is not needed for my application.

the other 6 pin (p2) I think is this one
https://www.rapidonline.com/truconne...-pitch-21-2844

Will try locally if I can't get them then will buy from rapid sure I can cut down a 6 pin to a 2pin if needed (Same pitch & profile)

e2a just ordered from rapidonoline as they don't have locally, got some CY cable as I was short so will have to wait for delivery but hopefully by Monday.

I assume I can use 2 core 0.5mm flexible cable from wilkos for wiring the AM882 drivers to the BOB?

They were the right connectors from rapid online, just got some cable for the signals but still waiting on the CY cable does mean though I can wire the BOB over the weekend, connect the power supply, PC and parallel port so easy job when CY cable comes.

I especially like the blood at the bottom of the case (Mine of course)

Decided not to go back today was sent some drawings from a solidworks designer and not happy at all I know I can draw them better in Fusion how we want them but not sure how lol.

Taking a while to get used to not having a co-ordinate system anymore and working from offsets but I'm hoping if I keep my head down I can get the drawings finished today.

I think in the old days you used to sacrifice someone else's blood.

Started the wiring today ;) Only going to wire up 2 of the stall protections for now (For the dual ballscrew) once it works we'll add in the other 2.

Attachment 23072

I'm guessing the plus/minus dir don't matter which way round they are wired and can be changed in Mach 3/LinuxCNC

Finally skanked a 2nd hand piece of ply to use for shelves almost having to go buy one there :)

Wired up a little more, now I need the CY cable so I can wire to the motors, limit switchs will go on last as I haven't even decided how to mount them yet past a brief look around the machine for ideas.

I think I might need to use the machine to make the limit switch mounts as I want them to be rock solid out of aluminium rather than 3d print them.

Attachment 23079

I hope I wired the emergency in correctly (Only 2 of 4 wired in at moment) wired them to a barrier connector block joining the live to live and neutral to neutral than ran 1 wire each to the right inputs on the BOB.

I assume it's similar with the limit switches, wire all the grounds to 1 connector and then from there to the common ground (same as emergency) then wire the limit lives. X&Z to the X input, One Y limit switch to the Y input and the 2nd Y limit switch to the Z?

I did ask before but forgot the answer what power should I feed the BOB
Attachment 23081

Looks like theres 2 PC live 5v's inputs, with 1 gnd, also 12-24v input and a 5v USB? Which one should I use? I'm going to have this sat next to the pc that will control it and I'll get a 4 pin molex extension to tap a spare output from the PSU so will have both 5v & 12v available.

5V comes from USB, 12 - 24V - external PSU. Same BOB was used on my previous Emco lathe.

But there's 3 pins bottom right marked PC GND and 2 marked PC 5v I was wondering are these inputs? if so do they replace the usb? I'm going to run a 4 pin molex from the PC power supply so have bother 5v and 12v to tap would be neater than USB and possibly more reliable?

It's nice that the BOB came with not even one piece of paper lol I had to google around to find that image or what looks like my board.

Perhaps, not sure. Mine used USB power.

Dumb question but the spindle has 4 pins marked 1, 2, 3 & 4 which is the ground? (I think it's 4)

To check if it's grounded do I just undo the bolts at the top and it comes off?

Should I just solder directly to those pins or is there a connector I crimp on?

Ring it out with multimeter. One of them should respond to the metal casing. If not, measure the resistance between the windings till you are certain you have the 3 phases identified.

Have the same BOB (not used it yet) and as I understand it you can have either the USB or the bottom connections for 5v.
The 12-24v connection is to be able to use 1-10v regulation for the spindle and perhaps the on/off signal aswell.. Will have to experiment :D

With these BOB's you need 5v AND 12-24v connected. It needs the 12-24v connected to get the inputs to work the 5V can be either be the usb or 5v I would use 5V.

Clive, you are a champ as always :D

Skickat från min SM-N910C via Tapatalk

I understand now, I think I'll use a molex extension cable to run one of power cables out the back of the new PC (Mini tower) then into the chassis with the steppers in it. Then run the 12v to a junction box and the 5v direct to the PC in and PC gnd. The 12v I can then split 3 ways 2 to pc fans to cool the stepper drivers and toroidal transformer and the other to the BOB.

The new PC doesn't have a parallel port (Doh! was watching a 3.4ghz it sold bought a 2.93ghz I7 assumed would be same motherboard and isn't!)

but does have 1 original PCI slot (And the rest PCI-E) so bought this
http://www.ebay.co.uk/itm/IEEE-1284-...72.m2749.l2649

Do I need a better adapter or will this be ok? The other adapters do seems to have more chips on them lol.

And the PC has a 8400GS 512 meg gfx card will this be enough to run fusion 360, looking around it should do but I'll have to turn shadows and some other effects off. This machine will only be used for CAM and controlling Betty (My name for the router) so don't want to spend any more than I have to on it. My home machine is my cad machine (Got a 760GTX in that, seems to power along fine).

Going to have to slum it with 4gb on the CAM machine for now but want to upgrade my machine to 16 or 32gb next month and then can rob the 8gb from that for the CAM machine.

Add on cards are hit and miss. Some work first time, some are a struggle, some never work.

At a pinch I can use another PC for controlling the machine which might not be a bad idea anyways.

Try it and send it back if not, eBay always sides with the buyer lol.

I'm happy with the price lol £90 for a 2.93ghz I7 desktop with 4gb of ram will do fusion 360 nicely I think for a CAM only machine. I'm sure I can get the parallel port working just wondering if this cheap ass card I bought works like a winmodem in which case it's probably useless for a CNC machine. If that's the case I might buy another card or more likely just grab another PC for the controller have a few motherboards kicking around with CPU's, ram and parallel ports on them.

Thats what i meant return the card if it doesn't work :D

It was £2 (delivered) for the PCI card lol got PC this morning, just set it up and installing windows 7, then we'll see if the GFX card works with fusion 360.

Still waiting on my 1.5mm CY cable for the spindle (Didn't order enough last time) will be tomorrow.

Itching to get it working, but got 1/2 of it wired now, really need to sort the limit switches out but need to machine to work so I can manufacture the parts (Out of aluminium obviously) as I need to guarantee repeatability for my plan to work.

Ah ok haha.

I just semi-finished wiring again for the second time, Proximity sensors i had were NPN & not PNP. What are the parts like? I could 3D Print temporary ones for you.

Alex

Little bit more done today, limit switches are fitted directly into the aluminium extrusion

Attachment 23122 You can just see the red microswitch at the end of the energy chain a Hiwin carriage triggers it, there's identical switch on the other side in same position.

Attachment 23123 And just under the bolt in the energy is the other switch only one bolt at moment need to find a 5mm piece of aluminium so I can fit the 2nd bolt but the edge is tight against the Hiwin rail so it's solid.

I drilled them tapped the holes, very happy how they came out. There is no Z axis switch yet will rebuild the Z axis so they will be added then.


Power supply is ready to be hooked up to the AM882's

Attachment 23124

AM882's now have all the stall protection wired in
Attachment 23125

The PC to control this now has windows 7 and Fusion 360 on it, and a parallel pci card installed. Wiring is in the energy chain just need to connect everything up, earth the spindle and connect solder that up and we can get it running.

Need to get some wiring for microswitch just going to use cheap 2 core a junction box to split the power from the home built PSU to 4 steppers and some connector plugs will pick up on way to work tomorrow.

How should I connect the CY cable to the nema cable, soldering or connectors?

Looks ace mate good progress! Is there anything special needed in order to enable stall protection on the drivers? I have the same ones but only have them wired normally at the moment, remember seeing in the manual that it said it only works above 300RPM.

I soldered my CY cable to the motor wiring, make it easier for me as i was going 8 wires into 4.

Just wire the output to the emergency input on your controller board then if it's missing a step the machine shuts down. You can see it's the 2 wires for stall protection next to the direction outputs on the AM882's.

On my controller I had to wire them to a connector and then to the emergency input on my BOB as I have to cram 4 wires into 1 emergency socket, it's worse for the ground I have to cram at least 7 wires into 1 lol.

Quickie question, I'm sure this is ok

I have 3 microswitches at moment 2 on the Y axis (Dual ballscrew) and 1 on the X axis, I want to wire from the Y axis microswitch to the 1 of the X Axis microswitches in series and then to the BOB X input and the other Y axis switch to the Y input is this ok?

I would keep the Y switches on the there own inputs . Can you sketch a circuit of what you intend to do?

If I understand you correctly it would work but you will only be able to home one axis at a time.. this is something I think about aswell for my build.
The way I think I'm gonna go is with one more bob to get inputs to use them separately :)

Skickat från min SM-N910C via Tapatalk

Got the limit switches wired up and the Y axis limit switch cable fed through the energy chain which meant removing it, it's a very tight fit ;)

Spent ages on little bits like making sure the CY cable is well supported, cabling is fed nice and neatly back to the control box.

Also spent 2 hours stripping some copper radiator water cooling units from a massive control box going to keep one to cool my spindle and sell one they're chunky things.

Going to go back in an hour and see if I can get the CY cable and spindle cable on tonight and move the PC down and connect up the power, etc. So tomorrow morning I can start playing, need to think about where to mount my VFD and copper rad.

Go-go desertboy! :D
