PoKeys / homing 2 motors one axis

« on: June 24, 2020, 07:34:34 AM »

Hello,
I am using a pokeyes57cnc with mach 4
I have a homing switch for each axis (shared with limit -). It works great for the X and Z-axis.
For the Y-axis though it will only use one motor to get to the switch, aka the motor that is programmed as slave does not move. This forces me to push the emergency stop every time. Does anybody know how to solve this issue?

Motors 0 and 1 outputs are used for the Y-axis and the Limit - 1 is used as the homing (and - limit) switch input
Motor 2 output is used for the X-axis and the Limit -3 is used as the homing switch input
Motor 3 output is used for the Y axis and the Limit - 4 is used as the homing switch input

Thanks a lot,

PoKeys / Mach 4- Pokeys questions

« on: June 14, 2020, 06:26:57 AM »

Hello,

I am new to mach 4 and Pokeys and I have a few questions.

1) I managed to setup my motors and limit switches (+ and - switch for each axis with the - switch used as home switch as well)
During homing, it wil home one axis and then stop moving as it says - limit tripped. It does not move away. How do I get my machine to reverse a bit and not stopping everything because a limit switch is activated.

2) I use a popendant, which works fine only the direction is reversed, how can I correct this.

3) I am using a VFD to control my spindle and I am using both relays to control direction Spinde Fwd Relay 1 and Spindle Rev Relay 2. I also connected pin 17 (0-10V) to correct input on the VFP but cannot control the speed. My VFD is correctly programmed. Spindle speed is set to max 24000 and in the spindle tap of the pokeys plugin pin 17 is programmed as I read in this forum. What am I missing?

thanks a lot,

Joris
