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.

Hi Olli
Thanks very much, for both the efforts you have put into this project, as well as looking at my Modbus issue. If you can PM me your postal address, I would be more than happy to send you one of the Modbus boards to use as a test.

I got the tangbob boards made and assembled by JLPCB for approx $100 for 10 boards plus freight - I live in North Queensland, Australia. They did quite a good job. I had to supply and place the tang board and the wiznet board myself.

Regards
Andrew

Can't really get into a debate with americans about language cause they wont know how to read it....





Never heard of silicium.

So tell us what you really think tommylight.
