General Mach Discussion / newbie - help needed please
« on: March 03, 2012, 12:47:17 PM »
Hello,
My name is Thomas and I just started playing with steppers and Mach3. It seems that I can't get anything to work right now... help would be very much appreciated
... I have no experience at all using Mach3. Datasheet for the stepper and the references for the board/drivers is attached.
In Mach3 (R3.042.040, running with XP on an up to date computer ... I installed it, rebooted, ran the driver test: freq. is 25kHz, it says "System Excellent")
-I have setup the correct address (0xccc8) for the port after checking it in my device manager
-I have modified the Estop to "active low" in Ports and Pins/Input signals
-I have modified the Step pin# and Dir Pin# in Ports and Pins/Motor Output using the breakout board specifications
- I have wired my FL86STH80-4208A (8 wires, 4.2A) in bipolar (parallel) connection... I also tried bipolar series and half coil connections - same result
-when I try to run the simplest G-code possible (X100) I get irregular, small steps. I can get the motor to step the other way by running X-100, but the steps are also small, and irregular...
As far as I know the connections between the breakout board and the driver are fine (checked 3 times).
If I look at Mach3/Diagnostics "Port 1 Pin current State" Pins 4,5,6,7,8 are green
I tried to install Mach3Version3.043.022 instead, doing everything the same way as before, and in this case I don't get any steps at all... and all pins are black in If I look at Mach3/Diagnostics
Is there anything obvious I am missing?
many thanks for your help
Thomas
the power supply should supply enough power (36V 10A), the driver is set up at 4.2 A (I guess it should be higher given the bipolar parallel connection) - I will change that later
data:
I use Version R3.042.040
my stepper is a FL86STH80-4208A (8 wires, 4.2A)
I have setup my 8-wire stepper in bipolar (parallel) connection
the breakout board and drivers are here:
