@DC42, you are so right !
I didn't uncomment my new M584 comment I would like to use with the external drivers.
M584 X5 Y6 Z7:8 E3:4 ;!!! SET mapping to external !!!!

"working" HBS57 settings :
M569 P5 S1 R0 T6.0:6.0:6.0:6.0 ; driver 5 goes forwards, requires an active high enable, 6us min step pulse, 6us min step interval, 6us DIR setup time and 6us hold time=E3 extensionboard =Xa
M569 P6 S0 R0 T6.0:6.0:6.0:6.0 ; driver 6 goes backwards, requires an active high enable, 6us min step pulse, 6us min step interval, 6us DIR setup time and 6us hold time=E2 extensionboard =Yb
NO ENABLE wires connected!
(no smaller values tested)

R1 setting generates Red LED error on HSB57 driver.

#problem solved# Thanks.

Have you tried R0 instead of R1

Thanks for your reply, it's very much appreciated.

Yes I tried both also with increased numbers.

No-power= free movement
Both setting R1 or R0 lock the steppers. (so that's possitive ;-))

However homing X shows the following problem.

I checked the wiring of the stepper coils A and B, according diagram and measured.

The enable cables are both disconnected on the external drives.
i tried :
ena+ and ena- connected => red led on driver
ena+ connected not functioning no warning (same phase error!!)
ena- connected not functioning no warning (same phase error!!)

any suggestions are welcome.... (my current clossed stepper setup is still a non-moving machine ;-((

Anybody out there; who has a working M569 setup of this type of external drivers...??
Thanks for your time and help.

@T3P3Tony

OK thanks ,
Case Solved !!

@Veti

Its a around 35kg;
I just picked the highest gear ratio possible for a nema17.
Just started with your 12mm/min setting.

The 20.000 steps start working as soon as you interpolate Z128, but Z256 is better for my hearing.
I also calculated the steps/s/axis, which which should be <130K/s/axis

So when z speeds hit the limit...I lose my browser connection.
No stalling Z steppers with the working configuration in the table.

So problem solved !!
20.000 steps/mm are possible...
Thanks for all the help.

@JoergS5
The first M350 is set without interpolation.
Than M92 is set... steps/mm
For the following M350 with interpolation, the steps are recalculated.

An yes it works, calibration stays intact with Z256 or Z128 defined with interpolation if you do it this way.

Correct I am only moving the z-axis (Za,Zb)
My M92 max value is 2640 , close to ~2900

But why is this reason to lose connection on the network card??

Maybe my first test at 1000 was a short time span and it homed..., and I didn't spot the connection loss.
first you lose the speed indication ...which is followed by the connection lose.

130Ksteps/s/axis...that's intresting,
just posted a problem how to do 20Ksteps/axis......so that should be possible! But How??

Web Interface Version: 1.22.6
CoreXY, double Z steppers with high gear ratio (1:100)

My machine is moving/homing, but the z-axis calibration is off..
The reason is clear... I need 20.000 steps/mm @ microstepping=

when using micro stepping I need even more.

All these setting are instantly stalling my Z steppers.
So I tried multiple settings;
https://docs.google.com/spreadsheets/d/1WQInFltVn53VTwnOhfARGDKM5ehv-s_keJl6v7CKaBk/edit?usp=sharing

It's the double problem of not stalling the stepper and also having the correct steps/mm for Z axis calibration.
This is so far the best setting, I found...
config.g

But the Z calibration is of by a factor of 20K/2640=7.57.

Any suggestion ??

Connection lost by M203 setting ?

CoreXY, double Z steppers with high gear ratio (1:100)

During my Z axis testing of the machine... I experienced my first "Connection lost" of the web interface.
This one was not generated by switching of the board power, but by a "change" in the M203 Z-setting in the config.g

For my board and network setup, it's reproducable.

Maybe there is a simple explanation for this.. or just a setting;

Problem solved; Spot on !!

The micro stepping, is the problem.
Although the high geared motors (1:100) have a large number of steps/mm
M92 X80.00 Y80.00 Z20000.00 E420.00 ; set steps per mm

The micro stepping 16 and even 32 works fine... (I thought it was impossible.
32 is even beter...I was able to crank up my Z speed from F58 to F190 before the steppers are stalling.

Thanks for the great help!!
