All,

GRBL version 0.9 claims that it supports COREXY systems.

I have not succeeded in getting it to work. What I tried is to un-comment the statement " #define COREXY" in the config.h file. ...

Thanks!!!!!!!!!!

Your explanation is clear to me and I WILL take heed your advice and NOT try this although I might have been in the marketplace for another G540 after I did the...

I too had trouble getting on your site yesterday and just now 3:00pm EST TODAY

Not clear at all to me.

The drives are NOT connected together at their outputs. Each one is driving a SEPARATE set of UNCONNECTED windings on the motor.

Other than the inductive coupling...

I agree BUT if the drives are identical and driven from the same pulse input and direction input then they should be in phase or at least very close (less than) 10% since they are 10x...

I'm a newbie to CNC BUT am starting a cnc conversion of my minilathe. I have acquired an 8 lead stepper that I plan on running with the coils in parallel. I have also acquired a G540 drive. My...

Thanks to All for the advice and insights.

My current plan is to install the z-axis stepper as "blades" has done in an earlier conversion. I will not change the lead screw but will try to use my...

Blades

Thanks for your comment from direct experience.

One further question: I am thinking of hooking up the motor as you did BUT directly driving the existing z-axis lead screw. I'll remove...

Thanks!
Pretty INformed discussion from my perspective!

I am currently running a HF 7x10 in manual mode. I've removed the compound and added a manual crank to the z-axis lead screw. I like running that way BUT would also like to add a stepper motor...

Guys

My intent was only to share what was useful to me. What I didn't like about the wrench that came with my 7x10 was that it was a fat, open-ended wrench. It couldn't be left on the nut, so it...

I got it from SnapOn (online sales)Model # BOERMS17, about $24 including shipping. There are probably less expensive ones from others but I was impatient.

Although one of the most cited mini-lathe mods is the cam lock mod to get rid of the need for the a wrench to loosen and tighten the TS clamping nut, lots of us have not made this modification. The...

I appreciate the info. I followed up on CNCBrain and looked into Acme threads. I find my recently installed electronic vernier VERY useful BUT now plan on slowly adding steppers and perhaps...

Instread of replacing leadscrews with ball screws to reduce backlash so that stepper motors can be used to translate steps into accurate movement, why not directly use the output of the DRO with...
