PoKeys / Threading/encoder Problems with Firmware 4.4.19 in mach4

« on: February 27, 2021, 01:48:56 AM »

Anybody experiencing erratic pitch also on pokeys 57cnc after firmware upgrade? I'm using a 2500 tick encoder. It seems z axis displays a lag in following the spindle position since this update. How do you rollback firmware on pokeys card?

General Mach Discussion / Index/Timing/Encoder Pokeys57CNC

« on: October 25, 2020, 07:50:23 AM »

Hi, I have connected a mechanical rotary encoder on the lathe, connected to Pokeys57 CNC. The encoder is sending correct signals which I checked in the Poscope. Now in the MACH3 encoder configuration I chose "ultra fast encoder" in the pokeys interface...but i'm now struggling with the DRO to choose. Neither Strue DR0 (#39) nor the MPG 2 Count DRO (#102) are feeding any signal to the Index indicator and the STrue display in MACH3Turn. With DRO 102 i can at last see in MACH3Mill "Settings" that correct data is fed. What DRO do I have chose and what other configuration do I have to make in Mach3?

PoKeys / Problem with Home/Limit Switches

« on: February 16, 2019, 04:52:21 PM »

Good day, I'm using Pokeys57cnc. However, for some unknown reason, I am not able to have mach3 recognizing the switches. I have connected on pin 18 on the axis switch connecteor for the x axis the switch, so that when it is hit, low potential is on. On mach 3 I had selected as home ref switch pin 18, didnt work (showed no reaction to the chaning of the potential). I then switched to external dedicated, didn't work either. I then tested the additional limit swichtes connections, same there on pin 11. I'm sure I'm missing out on something, but I cannot figure out what it is. I followed the manuals of pokeys, to no avail so far. Any guesses?
