Upgrade? Chinese CNC Machine

NO.

If you are going to throw money at it get the separate drives.

More reliable and if one goes down you can replace it, if one of those Toshiba boards goes down the whole lot is toast.

Hey John I agree those boards are rubbish, what would you suggest he gets remembering his budget?

Getting there, thanks to one and all who chimed in with all the info it's greatly appreciated.

Attached is a short run video - I really should get the camera out before I start aye anyhoo I'm pretty sure you can pick who it is that's being engraved, all I need to do now is get the probe working i.e. retracting on touch not spinning the motor and twisting the probe cables in to a ball The finally motor tuning ended up at 400s 2500a 200v - my initial test of this setup resulted in a 100mm straight line on X and on the Y so with that, WOOHOO although I still need to sort the Z out, time to sit and mind melt over the mach manual

BTW the line art used for this came from my tattoo line art collection a job I did for a few decades before I got bored. . .

So if anyone is looking for anything in regards to line art feel free to let me know, odds are I've probably got something that can be worked on if not exactly what you want.

Like this? 3x M542 CNC Stepper Driver For Nema17 Nema23 Nema34 Motor +5 Axis Breakout Board | eBay if so that'll be a doddle, her who must be obeyed should only hit me two or three times at that money plus that means more money for longer screws etc as I want to build a bigger one now!!

That would certainly do the job and you can also run the steppers at a higher voltage (50v) with those.

Well done, I knew you would get there - with a little help from your friends! G

If your thinking about building a bigger machine then make sure anything you buy to get this one running can be used again with the new machine, will help keep the cost down plus collect parts for the new one quicker.
