Holding torque, working torque will decrease with rotational speed.

I don't know of a tutorial. All the settings can later be changed in the created INI and HAL files or by rerunning the wizard.

Maybe best to ask about specific entries or do what you think is right and then post the INI and HAL files.

i'm able to let the steppermotors run by linux cnc there is already a first live there
i like to add the mpg one for the 3 axis with a selection botton
ther is an example "mpg pendant" in the userguide on page 648 (v2.8) or page 540(v2.7) but here they talk about the parport how do i translate that to the mesa 7i76e cart
when i use the pncconfig i don't see simular names for the inputpins
how do i need to start ?

If you search for my "spaceship plasma" thread in about p 3 or 4 there is a full worked example for the 7i76e

maybe out off the topic
i have one set driver/motor hbs86H / 86HSE8.5N-B32 what i can controle perfect with the mesa 7i76e with time setting 4 times 5000
as an experiment i buy at aliexpress 3 TB6600 (40V/4A) low budget drivers and 3 nema17 steppermotor i see i need to change the time value to 4 times 50.000 what i also did the motors run good at low speed not at high speed they stop also with a high accelleration
i found nice old stepper phytron zss 80.200 2fase 4 coils 4V/5A for each coil place 2 by 2 in serie an try to let run only a low speed en very low accelleration
when i take an ociloscope and look at the output of the driver i see 2 nice square 90° shifted waves following the signale of the mesa output
how can i use the phytron steppermotor settings or something else what is wrong ?

Hi Everyone,
Just made some changes and adjustments to the work of others in this thread, so that the connector labels can be easily laser engraved. Changed fonts/text/spacing etc. to suit and make it easily readable. This was done in Rhino and converted to DXF so if you have any issues, just let me know., Hope it helps someone!
