Hello,
you provided too little info.
It seems like you need to increase precisison of the generated g-code or decrease required precision in qtplasmac
Did you read this below?

Hi Andrew,
thanks for the info and thanks for the offer, but it won't be worth sending to germany.
i'll find something to test it with.

The price is really great, especially when you consider what it would have cost 5-10 years ago.

@All You are welcome to market the boards commercially,
I am happy if there are sources where everyone can get a board individually.
The only condition is, if you become a millionaire, invite me for dinner ;P

I do not really understand. If I flash another bit file (obviously it has two pwm gen) it shows four lines. (that is not a fix, because I wanted to use a stepgen on pin4 and Pin17)

        IOPortTag & x"00" & PWMTag & PWMBDirPin,                 -- I/O 06    PIN 4
        IOPortTag & x"00" & PWMTag & PWMAOutPin,                -- I/O 07    PIN 17
        IOPortTag & x"01" & PWMTag & PWMBDirPin,                 -- I/O 08    PIN 5
        IOPortTag & x"01" & PWMTag & PWMAOutPin,                -- I/O 09    PIN 6

The version with one PMW shows only one line. One line seems to be "empty". 

        IOPortTag & x"00" & NullTag & NullPin,                              -- I/O 08    PIN 5
        IOPortTag & x"00" & PWMTag & PWMAOutPin,                 -- I/O 09    PIN 6

Is there something missing? I would have expected something like:

        IOPortTag & x"00" & PWMTag & PWMBDirPin,                 -- I/O 08    PIN 5
        IOPortTag & x"00" & PWMTag & PWMAOutPin,                -- I/O 09    PIN 6


Greetings Timo

p.s. Do I understand it right that the gpio.008 is not predefined connected for this pwmgen, but could have been used for something else as well?
I am still curious if the tags in the firmware would change anything in terms of use.

Now I put folllowing lines in the .hal (particular unsecure if the setp is what is to be done)

setp hm2_5i25.0.gpio.008.is_output 1
net spindle-ccw spindle.0.reverse => hm2_5i25.0.gpio.008.out

That switches the polarity on the TB3 pin4 and TB3 pin5, that again changes the direction of the motor.

Do not fully understand why it does not switch between 0 and 4.9V. It switches between -4.9V and 4.9V.
 

Hello,

Thanks for your suggestion, as its working properly, I am able to run both Z axis perfectly. 

Cleaning almost complete.
Now I will clean each sub assembly, replace the bearings.

Here is an extended version of something that helps sum that up. watch the first 1min 56sec of it, then it just repeats after that. I can't
find the regular one anymore.
