At which point that also popped straight away, its as though there's a dead short in the driver. Is there anything obvious that i could check inside the driver before i wax another 50 sheets on a new one? I did notice a tiny bit of metal swarf on the pins at the dip switches(pic 3) which i suspect may have done it(whoops a daisy :) Thought it a bit strange that it was going so well! Drivers are 2m982 btw.

I've had a nice week in the sun doing nothing but think about CNC(sad eh?) So having sorted out a speed issue with kind help from Jazz, I was presented with another problem. Severe vibration on the gantry axis. This was caused by loose bolts holding the rail to the rail support(these were from chai). So having stripped down my gantry completely and trying to tighten the offending bolts, this is what I found:

Nearly every bolt had been stripped during assembly in china. So were basically doing nothing. My bad for not checking first. But after having re-tapped the threads and properly putting in new bolts. Everything is hunky-dory again......Phew! Suppose you get what you pay for in this game. I really wish I had dumped a few extra hundred quid and gone for profiled rails though. Maybe Santa will will bring me some along with the new spindle Ive requested from him :welcoming:
I had them work loose on my rails, but didn't see any damage to the screws. Did you threadlock them to make sure they don't vibrate loose again?
Yep, all glued up and nice and tight. Just waiting for a new driver to arrive from china now, seems to be taking ages. Then hopefully I'll be cutting soon.
Hi Jon, new to this site and come across your project. It looks great! Was just after some advice really, been looking at buying an off the shelf solution but after coming across yours I am interested in possibly making one myself.
would you be able to give me a rough time scale and cost of the project (excluding base) and how you went about designing it.
i would be confident in the mechanical side but the electronics and calculations seem a bit daunting.
if you don't want to discuss costs etc over the forum my email is [email protected].
Would really appreciate your advice.
Thanks, Dan
i'm glad someone has bumped this, how are you getting on with this fella?
Jon, that machine looks fantastic. In the photo it does not look like the bed framework is connected to the new centre legs, if not would the bed be more stiff if it was bolted to those legs?
Once again, congratulations on what looks like a super build. G.
Jon,
Excellent build! An inspiration for my MkII after I finish Wobbly. Keep it up!
Rgrds
Patrik

Sorry for not posting or replying. I've been dealing with a terminally ill family member so haven't had time for much of anything the last couple months. I actually got the machine finished around the end of November but have yet to cut anything significant on it other than a few signs for work. I started leveling the bed and realized I could really do with a fly cutter as opposed to a quarter inch router bit, and left it at that. I'm totally happy with the speeds and everything though. Hopefully soon i'll have a bit of time to play with it! Think the first thing i'll make will be a touch probe and maybe a belt drive mech for the z axis.
The machine took about 6 months from design to finish and I would estimate a cost of around £1500-£2000(cant remember exactly) - all in. It took that long because I was buying bits every month. If you had all the parts ready I'm sure it could be done a lot quicker. I used Rhinoceros(and Rhinocam) to design it. If you're planning a build, the best advice I would give you is to read, read and read some more. Post your designs, get a second opinion and be prepared for constructive criticism and design changes. Also, make sure you're 100% happy with the design BEFORE buying any parts - will save you money in the long run. Good luck.
thanks for coming back to post given your recent problems dude.
i took a lot of inspiration for my build of the back of this thread and i thank you for that and again thanks for coming back to update.
what is the spindle you are using and any reason why you choose that over a water cooled one?
The spindle was simply a router i had lying around. In all honesty its no good for this, it's only 1kw, but will do until I can afford a water cooled one.
Hi Jon, would you be able to send me some size data on your build. Im new to CNC and I do like the way you have done your cnc.
If you could email me jamie.qld AT gmail.com
Can you also post an update on your build, how is it going, what would you change if you did it again.
Regards
jamie
Anyone from this "theme" still active? ... I'd like to see any sketches or plans ... if it's possible
realy no one have any information about this machine?
Hi Folc, no i dont think you will find any plans for building this exact machine, however you may find this machine A Sturdy Steel Framed Machine Design to your liking and this dose come with the information your looking for.Quote:

Hi Folc, no problem if you need any help or need to ask some questions, please start a new thread and I will keep an eye out for it and help you if i can :beer:.

I know its an old thread, but does this run with 1 ballscrew per axis? How does it run?(if you still read the forums! :))
If you look back through the thread it uses 2 screws on X one on Y an the one on Z.Quote:

Nice Build! I see that you mount the rails of the z axis in the plate. its better? (sorry for my english)
Good night guys my name and Nivaldog43, I'm starting today, I found this post on Pinterest where I participate, I entered the site I really liked the CNC article that uses Rectangular tubes of weldable irons, I have in mind to build a CNC with these types of materials that are cheaper than aluminum, it is more reinforced depending on the wall thickness of the Rectangular Tubes, I have my appropriate tools to carry out this form of project, and I would like the moderator if he is not uncomfortable and if he can pass me the measurements he used for his CNC for me to have an idea of how much I will spend on footage of Rectangular Tube Iron Bars ... Thank you in advance ... I look forward to it.
