Build Log: 4'x4' Moving Gantry CNC Router

[Neale]

My first reaction is that 36V is a bit on the low side for a machine of this size. Something nearer 65V with drivers and appropriate motors to match would give much better performance.

Hi All,
Can't believe its over a year since I updated this. I got the opportunity to move the the US with work so the CNC had to go on the back burner for a bit.

Neale - Good shout with the power supply being on the low side. I bought that stepper kit before really knowing anything so its probably not what I would go for ir I was buying again. I'm planning to get it up and running with the power supplies I have but will probably look into putting a larger one in.

The mechanical design has gone through a number of changes and fluctuating goals but I've now got my mechanical design to a point where I am generally happy with it. Losing access to a workshop or garage has meant the size of the machine has needed to drop quite a bit. I've just recieved the 80/20 extrusion for the chassis and the aluminium plate has mostly arrived for the X and Y axies. This has all come as remnants and offcuts from eBay.



Here's the controller mainly wired up testing with the little machine I scrounged.



Cheers
George

I see you are running 2.7 linuxcnc is now on 2.7.14 so might be a good idea to update the version. Good luck with the build.

Progress has been pretty slow but still chipping away.

CAD now looks like this:
