Pete, thank you very much for the input. I appreciate taking the time.
You are right. I shall first try and diagnose than blindly shooting from the hip :P
I think I'll get that mechanics...

John you are right, the gantry does not have a plate against the back of the extrusions, just the front plate you see.
I'm not really sure what you mean by the "inside edges of the extrusions".
The...
Thanks for your compliment!
Yeah I realize there's somewhat limited view of the construction.
I attached some images of the design to help.
The backbone of the construction is all aluminium...
Hi everyone,
I have build myself a CNC router (see image).
The frame is constructed from aluminium extrusions.
I mostly mill aluminium parts on this machine.
The frame is quite stiff, however...
So I have some interesting results.
I measured the diameter of my tool using 3 methods.
1. Taking a pass on the right hand side of stock, then left hand side. Then measure the part across the cut...
Yeah it's pretty consistent so far (same cutter - same material).
I have been doing the negative stock to leave trick with success.
However I do want to find out what the root cause of the issue is...
I do repeat passes on very feature of importance to make sure that tool/machine deflection is kept under control.
I have not measured the endmill size precisely yet. If it is undersized does that...
Hi All,
I have built a custom CNC router.
In external features (e.g. bosses) I manage to hit tolerances of +/- 0.05mm
In internal features (e.g. holes / pockets) I get a poor tolerance of...
Understood!
Any tips for improvement with the current set-up? I am in no position to restart the wiring as we stand with the proper ground plane and clamp. In particular how can you do a panel mount...
Apologies for the delay. Had a hectic work week :)
Here's the visio wiring diagram: https://we.tl/t-v2vqJsG2a6
Unfortunately I left it at a semi-finished state (....as you typically do with...
Thank you man :)
I do have a wiring diagram yes (bear in mind I am not an electrical engineer though). I need to find a way to access it because I created it in Visio through my previous work and...
Thank you Mactec54. That's a good explanation.
I have 1 mains AC cable coming in the controller through an IEC connector which is then distributed by DIN terminals to the following PSUs:
-...
Thanks for all the answers guys.
My motor has the drain connected to ground only on one side (controller side).
Can you explain a little more about why the "pigtail" wiring is a bad approach?...
Hello,
I recently finished building my controller for a DIY router machine (image attached).
I am using 3x these closed loop steppers:...
