Re: MF70 CNC Conversion
Thanks to your excellent instructions and easy to assemble hardware, my MF70 cnc project has been a success. New to CNC, I now face the software workflow issues. I understand the theory well enough: CAD --> CAM --> GCODE (Mach3). Unfortunately practical recipes are scarce. People post videos, equipm...

Re: MF70 CNC Conversion
Good news!
With my multimeter, I found that the Parallel port cable had a defective pin
With a fresh cable and the EPP setting the Jog test now works on all 3 axis

Re: MF70 CNC Conversion
I checked the BIOS. I changed the setting from "PS2 mode" to "EPP mode".
The symptoms remain the same.
Could I have a defective Sainsmart board? How would I check it?

Re: MF70 CNC Conversion
I went to the Mach3 Jog screen. The Y-axis LED blinks on Y+- The Z-axis LED blinks on Z+- The X-axis does not blink. It cannot be a simple port driver issue.
I'll checkout CNCZone. Has there been any discussion of this project over there?

Re: MF70 CNC Conversion
1. You have to be using a true parallel port. It can not be a usb to parallel port converter. I am using a true parallel port. I even installed a 2nd PCI port which has a different address. 2. You have to make sure the parallel port settings in XP matches those in the drivers and config (Ports and ...

Re: MF70 CNC Conversion
I've set everthing up as descibed in the Servo articles. I tested all connections for continuity. The 24v is present and the red LED's are lit on the Sainsmart3 board. I'm running Mach3 on a Dell running Windows XP with parallel port. The port driver is installed. I checked the devices screen. Mach3...

Re: MF70 CNC Conversion
After reading your series, I bought an MF70. A very useful little machine. I'm eager to follow up with your CNC conversion but I have a few questions. Parallel ports went extinct with the Dodo birds but apparently the CNC crowd never got the memo :smile: I assume the Smooth Stepper USB goes between ...
