Protecting My Mesa 7i76EU: Wiring Questions for Home Sensors and Touch Probe

The longs motor DM542A is better than you think and is my choice of drives for NEMA23 motors if price is important.
With 25x microstepping and 48v power supply, I used the following setttings

I started getting joint following errors after I changed the following stepgen timing settings to these even values:DIRSETUP = 6000
DIRHOLD = 6000
STEPLEN = 3000
STEPSPACE = 3000This happened even though I set STEPGEN_MAXVEL and STEPGEN_MAXACCEL to be 25% higher than my MAX_VELOCITY and MAX_ACCELERATION values, as recommended.However, my power supply is a 32V 10A unit running three axes, so it might be a bit underpowered. Could this be the cause of the joint following errors?
I do have another similar power supply available, so I could use it to power one axis separately—this would help with the available current, but not increase the voltage.Any advice or experience with similar situations would be appreciated!

Can you post your complete hal/ini files?

Ofcourse! 

I've included them as an attachment.

I hope you have some good insights into my setup. 

Thanks in advance.

EDIT:

I now also use the following step timing:

DIRSETUP   = 500
DIRHOLD    = 500
STEPLEN    = 1000
STEPSPACE  = 1000
STEP_SCALE = 1000

In addition, I changed the |DISPLAY|MAX_VELOCITY and the |TRAJ| VELOCITY settings. I have also increased the other velocity limits accordingly.The machine is now performing better than ever!
Surprisingly, I'm no longer getting any following errors—I'm not entirely sure why, but I’m definitely not complaining. ?Thanks to everyone for the input and suggestions!
