Problem with MESA 7i76e and DQ542MA drivers

It may be that you are trying to run the motors too fast.
Try halving the speed and accel to see if that helps (purely as an experiment)

What is your step-length setting?

STEPLEN is set to 5050, which is what is suggested for my drivers. I will try to reduce the speed and acceleration and see if that helps.

The noise problems are because of the hal and ini settings
Changing P term to 1000 and removing the max-error settings on
each axis will fix this problem

Ok, the change to the "P" to 1000 and removed the max-error and it worked. Thank you guys (PCW and tommylight) and so much

Anyway, I still no not understand why the generator put the 10000 in there. I think I never changed it

Now I'm fighting the speed, it seems to move very slowly... any tips on how to increase the speed? Everything I try to do seems useless and the speed seems to stays the same

I have these Drives with a 7i76e. Disconnect the +5v from the enable terminal on the stepper driver.
What is never made clear is the the enable signal is actually a dis-enable signal. Putting power on this pin will disable the driver.

So I have it wired into my estop circuit so it disables the drive if you hit estop which allows you to move the drives by hand.

That makes sense I will disconnect the +5V from the enable terminal, it is doing nothing anyway since the GND is disconnected, Thank you.

I apply 5v on enable pin when power is applied to the system. Only when the machine-is-on I remove it via a relay. That way they are disabled until the machine is turned on they get enabled. upon an e-stop the relay gets denergized and the drives are disabled.

Sounds like a good method. I might try it.

One more issue, I upgraded to 2.8 and everything is working fine, except I cannot seem to be able to get my Y-gantry to move properly with 2 motors, only 1 motor is moving

Anyone can tell me what am I doing wrong with my INI and HAL?

Here are my files:
