General Mach Discussion / Rotary Setup / Feedrate questions
« on: July 11, 2017, 10:31:41 PM »
Hi,
I setup a 4th axis on a china cnc 3040 cnc. Everything is working after replacing all of the electronics and building a new control case to fit everything in. I have 10 steps per unit and 75000 and 25000 in the motor tuning page. I command A 360 in MDI and get 1 revolution and decent speeds when jogging so it seems all is well but when i run a program with a and y together at a feed of 100 the axis are barely moving (like 1 min to move 1/8 of an inch). I currently have a feed rate of 7000 with FRO set at 250 to get a 'normal' speed. Is there another setting somewhere that needs to be turned on? mach 3 version .066 running through parallel port and setup units are in inches and program is inches. Also i have set the federate to radius option under tool path and set radius to 1 inch on the settings page.
Thanks,
Matt
