Hey Ya'll-
After much drooling over everyone else's CNC success with the Grizzly G0704 i've decided to start my own build.
Today I was attempting to hookup and test my stepper motors but I'm running to trouble. Nothing moves!
My gear is as follows,
- Old POS PC running windows 7 32bit and Mach 3.
- This PCI LP1 Card SYBA Model SD-PCI-1P PCI to Parallel Port Card Add-On Card - Newegg.com
- KL600-48 power supply
- MX3660 driver and BOB
- Nema 23- 570 stepper
I have the MX3660 being powered by 48V (verified by meter). It powers up fine. When the MX is powered up I here a clicking noise from the stepper and I am unable to move the shaft (good news right?) I have the e-stop circuit jumped to eliminate the Mach error. DB25 cable from the MX to computer has been pinned and all pins show continuity as expected. Under Mach's ports and pins setting I have the correct location 0x378 (LP1) chosen. This has been verified in windows device manager. Under Mach's motor setting I have the rev's per set to 2000, pulse uS set to 5 and dir uS set to 5.
When I bring up the jog screen (tab) and press the arrow keys to job the X-axis the stepper which is connected to motor 1 of the MX, it does not step. I have read in the MX3660 manual that pin 2 is pulse and 3 is direction. These have been set correctly in Mach for the X axis. I have tried the "Low" toggles on and off to no avail....I'm beginning to think my Parallel port just is too "Modern.........".
Any suggestions?
I'll be sure to post pictures as I continue my build.
