General Mach Discussion / cnc usb 5 axis controller
« on: October 30, 2014, 11:29:54 PM »
Hello, i have one of these little guys:
http://www.ebay.de/itm/CNC-USB-5-Achse-Axis-50KHz-Mach3-Schrittmotor-Schnittstelle-Breakout-Card-D-/121423661339?pt=Motoren_Getriebe&hash=item1c456a091b
A smale usb controller ... that should work with mach3 (as it says).
So it is really working for me. I hooked up all stepper drivers, installed the plugin into mach3 and it drives my machine.
Also the digital input and output pins are woking.
I was able to wire the reset switch to it.
But now i ran into problems.
First of all... softlimits are not working??? How can this be???
I was thinking this is controlled by mach3???
And i hooked up some limit and home switches (6 switches, on all axis home and limit-- is the same switch). I was not able to make this work.
It triggers the limit switch alert everytime when the axis is running against the homeswitch (as i said, same switch, same pin).
On the diagnostics screen i can see the switches are configured as home and M-- limit. they are triggering the right the input signals.
I think shielding and debouncing will not work here....
The only way i can run this is by disabling the limits-- and only leaving the home switch enabled.
But that is a really bad soulution, because the softlimts are not working.
I can set the softlimits and also they can not be activated if the machine is jog outside these limits.
The limits have no affect no matter if turned on or off the machine does not slow down or stop.
I think the only way might be buying a new contoller.... any regards or brands? i really want a usb controller (not a usb to comport one / like smooth stepper)
thanks for reading and any ideas
