TB6600 and new motherboard.

Hello.
I builded new computer with LinuxCNC (motherboard MSI Z87-G43). Axes X and Y: M542 drivers, axis Z: TB6600 driver. Board: SSK MB2
Axes X and Y work perfectly but Z axis doesn't move.
On previously (very poor) computer all axes worked fine.
Settings on StepConf:
step time: 5500,
step space: 5500,
direction hold: 20000,
direction setup: 20000
max jitter: 2500.
Where is the problem? Software or new hardware?
Thank you
Marcus

You really need to check both the hardware & software.

You could try increasing the step time & space for the Z axis, maybe start with 10000 if that works, then try 7500, if that works go down half again, if it doesn't go up half, until you find the value that works best. Similar in method in how a successive approximation ADC finds a value.

eg:
If 10000 works try 7500 (if not try a larger number)
If 7500 works try 6250
If 7500 doesn't work try 8750
and so on.

If that gives no change:

Check all wiring. If all is good I would then do the following.
I'd swap the Z driver with either one of the X or Y axes and run a test. The idea is to check that the TB6600 driver is still good. If the Z axis does not work on the swapped driver, I'd recheck the wiring, then check the *.ini & .hal file.


If you post the .ini & .hal files that will.

Thank you for your response.
I changed the step time and space (2000-25000), checked connections, changed ports, motors, drivers - it still doesn't work. The configuration files are attached. Maybe you'll notice something there.
Thank you

Is your Parallel Port included on the Motherboard or is it an add in card.

Could you please run this command: and attach the lspci.txt file with your next post.

And and attach the dmesg.txt file with your next post.

.

You ok Marcus ?
Your last post appears to be blank.

Everything is ok, thank you
I will add the files as soon as possible.

No probs mate.

Something is odd in the config.
The step length and step space seem to be set to 1nS.

This is usual if the config is using the stepgen "reset" function, to allow 1 full step every base period.

But your HAL is not configured that way.

So, step 1, edit the HAL by hand to set all steplen / stepspace to 10000 then try again.

If that works, then we can work out what has gone wrong. If it doesn't work then we need to carry on looking.

What is the digital output used for?
