I'm making my own, machined and/or 3D Printed (where appropriate) x/y/z bearing/motor mounts, I had another member machine...
That mill has some really nice features!
The x and y screw mounts look very similar to those on a PM-25mv, and the bed is close to the same size, just has more travel on the z and y axis.
...
I checked everything with a multimeter, and voltages looked correct. 70-80C? I didn't check it with the ir thermometer, but that sounds close to what I saw.
I just finished machinging my x-axis mounts this weekend, and took some measurements of the ball screw- the ball screw length looks to be dead on.
(Things are slow going, I've only had time to make...
I have same issue. Tested out my AT steppers/drivers with UCCNC--->UC-100--->DB-25. The most I could get out of the motors was an occassional buzz, one of them got really hot...
I shelved that side...
its my understanding that you shim between the ballnuts to create preload when the holes are aligned. The z-axis already comes that way- shimmed in between and attached by the ‘ears’ for this...
I just went with typical recommendations for the G0704 machines: 570s on the X&Y and a 906 on the Z- I was going to use a 570 on the Z as well, but I wasn't sure if it would be enough as this is my...
I didn't check my ballscrew lengths, only tested the ends to make sure they fit the bearings and preload nuts correctly. I'm just starting to machine the conversion parts now.
If Z or Y are too...
Did you call or contact their customer service? I have a feeling that they would make it right for you.
I actually contacted them because I had ordered a set of end mills with my machine and...
The only issue I had with my PM-25MV was that I had to add 0.004" of shim stock into the bottom front of the column to get the y-axis to tram correctly and the Z-axis square to the table- its not...
A roll of shop towels, a can of WD-40, and an old tooth brush, the supplied tools, and a few hours of elbow grease were all I needed to make my Grizzly lathe usable.
If you can find a star bit of the right size which is a tight fit, it'll take the screw out. I remember reading somewhere a long time ago that hex bolts are engineered to strip out before any...
I have the grizzly 7x12 lathe, knowing what I know now vs what I knew then, I wish I would have put the money towards something like a 10" South Bend lathe. The small lathe works ok, especially since...
IIRC, it was DHL, and there was a tracking number.
ETA: I just checked my records... I ordered on the evening of 5/31, received the screws on 6/11, and was contacted by DHL with tracking info on...

They took about a week to get in from China, which was faster than I expected....
Those like really nice!
Are you using FK10/FK12 bearing cartridges by the looks of it?
I'm going down the same route, though I bought all of my electronics/motors/software so far, ballscrews came...
