Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
I agree with JazzCNC - loading the stepper motor bearings so much wont end well...
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
I lay awake thinking about that last night and came to the conclusion that I was kidding myself it would be ok and should have known better....I'll pocket it deeper and tension the belt from the side....or weld up a bracket from steel that can slide to tension it. Cheers chaps.
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
A bracket could be made to fit in between the top and bottom plates projecting back and lapping around the back face of the two plates ( like a tee piece) it would mean the motor is sticking out the back slightly.

"TOOMAST ..Do you have special machining on ballscrew? I notice longer area for the pulley?" Just order the ball screw with the "F" measurement 30mm instead of standard 15mm. ..Clive
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
Clive I'm going to pocket out the bracket that I've got and use that with a shorter belt I think....well that's the current plan anyway!

Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
Ok so pulled the gantry apart and machined the front and bottom plates (M8 counterbored hole in each)

Put it all back together and it's nice and solid...

Control cabinet and bits arrived just now so more stuff to play with [emoji3]

Going over to Wobblycogs tonight to have a catch up, talk CNC Routers and look at his control cabinet to get some inspiration...
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
OK quick question. I'm now coming to the end of the mechanical build so my mind's turning to all things electrical :cower:
When connecting the CY cable to the stepper how do you folks do it? I was thinking of either via a chocolate block as near to the stepper as possible or probably I'll go with soldering the wires with heat shrink over them and then heatshrink over the whole lot?
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
I'd expect soldering+heatshrink to be the most reliable way to do it.

Agreed it's the most hassle free way I find.!
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
Cheers, just thought that as long as the joins soldered ok then there's no potential at the join for a loose connection.
Next question! I'm going to get a safety relay (probably a second hand Pilz from ebay) for estops, limits, home switches etc. What's a good model to get, I've seen some Pilz PNOZ X3's which seem to fit the bill?
