Been a while since I was on this forum, have now moved into a council property, with no garage..! I have tried to build a wall mounted cnc but just cant get round the noise problem... So have decided to scale down to a small desktop cnc (400mm x 400mm). I could start chopping up my rails and ballscrews, but seems the wrong way to go about this...
I will compile a list of the stuff I have in more detail but roughly it is as follows;
2 x 2mt 20mm supported rail + 4 bearing blocks
2 x 1.4mt supported rail + 4 bearing blocks
2 x 25mm ballscrews (machined to fit nema 34 mounts)
2 x 25mm ballnuts
1 x 16mm ballscrew (machined to fit nema 23 mount)
1 x 16mm ballnut
2 x nema 34 mounts
2 x nema 34 motors (4 wire 6N motors)
70v PSU and two drivers for the nema 34's..
I will get specs and serial numbers etc later today or tomorrow...
As I mentioned, I am scaling down so these will be up for sale or swap..
Any more info needed, just ask!
Could be interested in the 2 nema 34 pm me a price buddy
Just the motors? I have the mounts, drivers and psu that goes with them too...
Yeah just the motors. Which drivers are they? Drop me a price for both bud
Bit bigger than I need but would have bought the job lot to save pissing about if it had been a tad smaller.John S -
Hi all again..
Wow, did not expect such an enthusiastic response..
I have my hands full with kids today, will supply all specs by tomorrow morning for you all.. Have had several messages asking me for a price for the lot, I will also work this out for you all too..
If any of you are up-sizing, I will be interested in a swap for a smaller machine/or parts...
25mm ballscrews are 2mts usable thread + machined ends (10mm pitch)
16mm ballscrew is 1.4mts usable thread + machined ends.. (10mm pitch)
I have not included all the z axis bits yet so the list is quite incomplete, really need an hour or two to catalogue what I have, and the kids are not giving time to draw breath today..!
Bear with me until tomorrow and I will have all info on everything...
Yes, 1,4mt rail is 20mm, more info to follow...
Ok, think I have managed to compile a pretty comprehensive list.. All these parts were bought from Zapp and I have tried to pull the details from the invoice and match them to Zapp's website. I have put a link next to each item so you can check it out directly..

Phew... That's just about it... I did not include the two nema 23 (3NM) motors or mounts as I am thinking of using them for my smaller cnc, but if you insist, then I will sell them too to make the package complete.
Also not listed here is the price I paid for machining the ends of the ballscrews (£320).
There are also 2 x PM752 drivers for the NEMA 34 motors. These seem to be discontinued on the Zapp site now but I did find the data sheet for them http://www.zappautomation.co.uk/down...vers/PM752.pdf
These cost me about £70 each, but am still trying to find the invoice for them..
This equipment has had about a years very light use, mainly engraving wooden boxes.. I have only used my router for wood and it has had only light engraving loads. I have cleaned everything, including dismantling the ballnuts and reloading them with new ball bearings.
A couple of you have asked me if I still have the gantries and z axis assembly. Unfortunately, I dont think that what I have will be of any use to you as I had to make a 12" high gantry to accommodate pre assembled boxes (which I engraved) for a customer. This meant the gantry was way too high to be rigid enough for 'proper' routing and was only capable of light loads. I was my intention to lower the gantry with a new design which meant mounting the rails (X) onto a hefty pair of RSJ's.
If anyone is interested, I still have these RSJ's (cost me £100 for the pair), they are 157mm square and just shy of 2 meters long. They have been drilled to take the supported rails on one side, and have 6 x 1/2" mounting holes on the other side. They are extremely strong and rigid and I reckon they will make very good mounting rails for the X axis. Will supply photos on request.
Whole lot cost me around £2700 inc vat...
Make me an offer for the lot, or will split if no takers for the whole package..
Any questions, just ask...
