Hello all,
I am in the process of converting my Taig Lathe to CNC. For a driver I have a Geckodrive G540 and Automation Direct Surestepper motors (166in/lbs) from Soigeneris. I'm trying to use Mach3 turn...
My problem is this: I can set up the steppers to the right steps per unit (40,000 due to the 20tpi lead screw on the x axis for example) and it does work, but so slowly it is not funny. I try a 0.05 move (one rotation) and it takes 20 seconds to do the one rotation... And that is using G00!
When I jog manually, the motors move no faster, even with jog at 100%/or shift key depressed. I see people on YouTube testing similar motors with the G540 and they spin in the hundreds of RPMs, yet mine crawl. What the heck have I done wrong?
Power supply is good, 7.3 amps @ 48v exactly as advertised. The motors are common enough and the DB9 connectors have the correct 2.8K resistor installed for their 2.8a draw...
I'm really stumped here and hoping someone else has solved the same issue. I was hoping to thread with this setup... At this point I would need a spindle doing 2 RPM to pull it off. Not going to happen obviously.
Thanks in advance for any help!
