Controller Card blocks additional axis in Mach3
« on: March 05, 2016, 10:12:24 PM »
Hi

I have a chinese 4-Axis controller card (XHC). I was trying to add a 5th-Axis with some brain commands for fast switching of an output pin, it should trigger when the imaginary axis steps. The problem is that this controller card blocks the movement of the axis. If I run Mach3 with the card disconnected it works perfectly, but as soon as I connect it again (without changing of any setting) it blocks all movement of the axis and therefore no braining possible. Is that normal that some controller tell Mach3 that there are e.g. only 4 Axis and therefore no movement for 5th axis possible?
Is there a way to trick Mach3 or the card?
Or is there nowadays another trick to directly trigger an output with a g-code command, without stopping other axis movement?

Cheers

The problem is not related to Mach3, you need to contact the manufacturer of your controller to ask them why the step and direction signals for the B and C axes have not been made available.

right, I will have a try to contact them, chinese company though  ;D

meanwhile I tried some other things. I made a brain watching DRO1000 which is set by var #15000. If I use MDI and type the command #15000 = 1 or #15000 = 0 it switches the output perfectly, bun unfortunately if I implement this commands in a gcode nothing is happening.

I basically need a solution to switch an output during movement, other than the imaginary axis solution. already sitting 2days to figure it out  :'(

If they've sold you a 4 axis card and also sell 5 and 6 axis cards that just might explain why their 4 axis precludes using a 5th ;-)

indeed, they are selling 6 axis cards but for the double price, nearly 300 bucks, pretty expensive for an imaginary axis  ;D ... will be my last option though. Still trying to find another solution
