Well power supply is connected to drivers and no smoke (thank goodness as Jazz would kill me). Fuses in place (using the fuse box I have until I can get the 5A fuse bars for the G bar fuse holders) and waiting on the 4 pin chassis plugs to arrive tomorrow (though I had enough and Maplin was out at the local store). So all things go well should have the base wiring done tomorrow and can test. Already have set A axis to slave in Mach3 and will triple check that before I run anything. So things are going to get interesting shortly (in a positive way).
Michael
well are you making chips yet
James
Ha ha James it's more like parmesan cheese Micheal makes with the tolerences he works too but I Think he's still wrapped up in spaggetti and knowing Micheal he won't cut corners or turn it on untill he's 100%. (Esp as most of the electrics are loned from me and he knows if he lets the magic smoke out I'm all tooled up . .:rofl:)Quote:

Don't worry I will have it running soon and will get video up as soon as I have the test runs video taped and then get some cutting on video.
Michael
Really really looking forward to seeing it run
But I know how it feels to strike it up for the first time and If your like me I was happy still to sit/stand and just look at it.
between you and me I was scared to death of it (I didn't want the magic smoke) plus I didn't have the right cutters or software but that's another story
James
Well Fuses for the G rail fuse holders arrived with the xlr 4 pin plugs/sockets so wiring that in and soldering what terminals I can together. Waiting on two 4 pin chassis plugs for the machine end of the Y and Z axis to finish that drivers all show power as well as power to the BOB all hooked up and wired in. So moving forward and making progress. Amazing the time it takes to just get the wiring done right (I am not even done yet really as it all has to be moved inside the control box once it gets here and leaving a bit extra wire for that). Well back to soldering up what needs done.
Michael
Had to cancel the online order from Maplin as it would have not been in stock till the 19th of March and thanks to Bruce giving me a lift to the Maplin that did have the plugs I am now to the stage of final soldering tomorrow morning and then tomorrow afternoon if I am able to get all ten plugs and sockets that need soldering done I will start on the test runs to see how things go and get everything moving. Hopefully I will have video up tomorrow night, if not Saturday will be test and running day to see how thing go and get ready for doing some cutting. I still need to get the X axis IGUS chain to help protect the cables and will be cutting the brackets to hold that in place. Monday I will be ordering some HDPE to get bolted down to the sub bed and surfaced. Once that is done and the test cuts done I will be very busy.
Michael
Too right you will. I need brackets, supports, holders ..........:rofl:Quote:

Well Y and Z axis are up and running and responding to both jog and direct co-ord's input. Working on tracking down why I am not getting lock on the A and X axis screws and hopefully will have video of a full functional unit later this afternoon. As it is 5m/min is rather impressive and the machine does not shimmy at all. Need to design some cable guides for the Kress cable that will also serve for when I up grade to a spindle. Tracking down wiring gremlins is not fun what so ever at all and even though I know I tightened wires properly they seem to find ways of getting loose. Keeping at it an hoping to be done with this part soon.
Michael
Things that small which weigh the same as a small car tend to NOT shimmy.!!. . . . . . They just try to TIP the shed over.:dance:Quote:

With 5mm pitch screws your near max rpm and less torque, your gantry ain't over heavy but it ain't light weight either so tread carefull when your approaching 5mtr/min. If you don't need 5mtr/min then I'd say back it off just for good measure.!
Great Build! If you don't mind me asking what is your total cost? And can you break the cost down to parts? And suppliers?
I really love this build, all the best today!
Well Folks,
It is late tonight and much chasing the Gremlins. It runs and is zeroed on all axi'. I will get some video up tomorrow afternoon or evening of it running out the test pattern I am going to be using to see how it handles different speeds. As Jazz suspected, when the gantry comes to a stop from speed the shop shimmy's a bit. Currently have gotten Y and Z ups to 3500mm/min no problems and Y an additional 500mm more without me getting to nervous (at 1250mm^2min acceleration it moves fast). I am tired and going to bed.
Michael
Fantastic:beer: I expect thats a good tired. Look forward to seeing the beast in motion.
bruce
Well Folks here is the promised video of some of the Test bed running I did today. This video takes it up to 4m/min run speed going in 500mm/ step ups from 2500mm/min start. I do not have video of the 5m/min run I did after that as was very careful with that one as did not want anything to wrong so had one hand on the e-stop and the other checking as able to do safely to insure nothing was over heating. Already have done a light tightening of the belts as was expected to be needed. I am going to be ordering the HDPE tomorrow for the cutting area bed and also a surfacing bit to surface it with (any suggestions up to a 8mm shaft would be useful (don't have 7mm collet but do have 1/4"). Then it is cutting jigs and parts. I will be posting more video as able.

Enjoy.
Michael
More fun than a train set eh! Well done Michael its looking good. I will pop in during the week.
Bruce
Looks good Mick I'm please for you now start making money to buy a water cooled spindle
James
:dance::dance::dance: No sweeter sight than seeing a machine come to life :dance::dance::dance:
Only wish I could have been there to see the BIG CHEESY smile on your face.! . . ENJOY. .:beer:
You got that right Jazz.:naughty: As you know from talking to me. Well folks at an acceleration of 1250 mm a velocity of 6.25m/min was safely reached yesterday. I have ordered an bottom trim from Wealden Tools (Ouch) which will give me a 35mm surfacing ability wit up to 12mm depth. Have ordered some nice micro plunger switches from RS and will be ordering some HDPE for the working bed and making jigs with, also a small section of acrylic or something reasonable in price, rigid and machinable to make the front and back plates for the control box (thanks Bruce it is working a treat). :dance:
Kylelnsn,
I am more then glad to let you know the materials that went into this machine. The problem is I got some prices on material that where one offs and I thank the folks who help me get them as it is allowing my business to stay in business and even do more than originally planned.
The Extrusion is ITEM and I can get you their price list, the Aluminium is from Ali' warehouse, ballscrews and mounting blocks and rails are from Chai off ebay (linearmotionbearings) Current power supply is on loan from Jazz, with the final being built in house. The Stepper motors are from Gary at Zapp and are the Nema23/4 3Nm ones. Spindle currently is Kress 1050FME and will be upgraded to a 2.2kw watercooled when possible. Current Bob is an older model PCPPS (v2) from Roy at DIYCNC. Drivers are three on loan from Jazz to be replaced by the same as the 4th which will also most likely be from gary when the time comes to get them (soon the better to get the bigger ones back to Jazz). The final BOB will be from pmdx and will be a version 126 or what the current version of that model is and once able to afford it a motion control card of smoother stepper (the ethernet based model). X axis rails I believe are also from Chai via James and Luke who kindly let me have them off them for the cost of postage as they made a change in their design and did not need them.
So to all who have helped with this project, my deep and heart felt thanks. I will add to this build some more as I progress and as it develops into its final form. I am extremely Happy :toot::dance::beer: at present and finding ability in this machine that the old one does not hold a candle to.
Best wishes to all on your projects and hope things are well in your lives.
Michael
PS there is more video just go to the one that shows the 4m test and you should be able to link to the 6m/min test.
Well,
First cuts being the surfacing of the bed. Here's the link folks: http://youtu.be/bxH6B8lXTjw
Hope you enjoy and once get cutting parts will get that up as well. The limit switches arrived today are are a good bit smaller than I thought they would be. Though as long as they work and do what was said they would do we are good to go the next stage and get things set up for the tool change and probe sections.
Michael
Ah what a lovely sound of tooth on wood. Nice one Michael.
bruce
Well the work bed is drill the inserts put into the sub bed and work bed bolted down. I will be making the g-code for the brackets to hold the homing switches and sourcing some copper plate for tool changer and Zero setting probe. Also need to set up the wiring for that and get things moving on. Will post pictures and links to the cutting later tonight. Been a long 12.5 hour day in the shop or office and not done yet, but getting progress and working well.
Also been working with the tuning of the motors and that has solved a few issues. It hums nicely now and no jerkiness with movement or making pockets. It feels real good to get this far and be at the point where cutting product is within sight.
Michael
Folks video of it cutting:http://youtu.be/dDnCwK3TLkc and here: http://youtu.be/T7EW02Mux_Q and here: http://youtu.be/wO1KkYz9oOU
Hope you folks enjoy. Will be getting a new 2mm acrylic end mill as one broke in the cutting of this project ( piece was able to get free and bind the endmill.
Will keep folks posted as thing continue.
Michael
Well a small but important update.
Home and limit switches cut and installed. Tuning of the motors now within needed tolerances (.02mm or less, repeatable), going to be tramming the spindle tomorrow as that needs to be done for doing large surface cutting. Then it is time to cut and cut and cut. I might not be on often for a week or two as I get all the cutting done, but will try to post some more video.
Again thanks to all the folks that helped with this.
Michael
Looking good Michael :wave:
Thanks for the vids and look forward to seeing the cuts later on !

Well some lessons that have been learned on this build:
1) It always takes twice as long as you think it will to get it done and done right.
2) Design the Machine at least three times and expect to do more.
3) Ask for critical reviews of what you are doing and keep notes.
4) Write down what you plan on doing with the machine and over build by 20- 50% (trust me on that one)
5) Account for wiring pathways when designing (IF you don't, it will bite you).
6) Account for lubrication points (See above, only worse)
7) Account for maintenance work on the machine (being able to take it a part and put it accurately back together is important)
8) Plan for upgrades and what they will be and why (few of us can afford high end equipment from the very start).
9) Be willing to learn (that means knowing when you don't really know something and finding some one who does).
10) Remember these machines are wonderful tools that will seriously mess you up if not careful.
That is what I have learned so far from the First machine (a bought unit) and this build with JAZZ. I am currently seriously busy with clients work and business projects so might not be on much but will do as able and will try to keep folks up to date with how this build is performing.
Michael
Being new too the forum I haven't been following the build but just sat & read through from the start. Very interesting read & a bit of an eye opener to someone who really knows nothing about designing or building a machine.
Good to see the conclusion as well & to know it is doing the job it was built to do. Hopefully Michael will have time in the future to update this thread as the machine develops further but customers have to come first lol.

Yep,
That was 2.5 m/min, though at that time I was only using about 500 mm/sec^2 acceleration. That and surfacing 850 mm by 350 mm does take a bit of time even at that speed I will be cutting some combs tomorrow and should be able to show what 1.8 m/min looks like in a small area. The difference being 1250 mm/sec^2 acceleration and using much higher quality electronic control hardware.
As it is need to be looking into a better swarf shield then what I am currently using or a way to improve it. The plastic sheeting I am using for the curtain is curling in at the bottom and opening gaps.
Michael.
aghh ! I hate metric ! LOL !
I surface mine at 120IPM, which I worked out should be approx 3M/Min for comparison, but mine seems to appear to move faster, than yours in the vid, so I was wondering if I got my translation wrong.. Although......, now I think about it....., I surface manually with the jog keys, so it would be 180IPM, which is approx 4.5m/min ?, which would explain why it seemed faster ! doh!!!
sorry ... as you were .... :)
Rich
Well,
Taking note from Bruce. My machine is now fully up and running minus the new power supply which is taking a bit longer than expected to get done (want to make sure I get it right). I have had a few minor issues crop up, but other then that it is running very well and cutting any material I have asked it to (Aluminium is no problem now just messy). I will be getting the design for the ducts collector shoe from Bruce and will be fitting that. Will trying out a few other materials over the week and will post in a different thread as this build is done with the afore mentioned exceptions.
I hope folks can learn from it and again a big thanks to those who helped as not only do I have a machine that does everything I needed when it was built but even more (which means things I did not think of can and have come up can get done as well).
Michael
