Maho MH800e Retrofit Project

Category: Milling Machines

ok here are my files and the reference file for the mh400e which was made about 5 or more years ago I think. I made a bunch of configs so I am sorry the name is the default I need to change it. again I think this is mostly working now short of a few bugs I need to test some things out and move towards wiring things to the mill

Can you create a small Python file (as simple as possible) that when I call it via REMAP = M6 modalgroup=6 python=remap_m6 , for example, only moves the Z-axis by 10mm

Just to follow on from Rod's comment.

Many of the UIs that are visually modern/graphical expect a 1080p display.  For example ProbeBasic imust have 1080p or larger.  The upside is a lot on a single screen at once. The more "original" or "old school" UIs expact much less with a 720p display being very roomy for them.

Re the comments on starting with Axis.  I would second that approach VERY strongly.   You will save youself a huge amount of potential frustration by having a working machine under Axis as your baseline.  That way when moving to another UI and you have issues you can better pin point where things are falling down when you KNOW you have a working Axis config.

Yes, 8mm/turn = 3.175 turns per inch so ~1900 RPM at 10 IPS
which is at the edge of stepper capability (at least with usable torque)

Perhaps the OP does not know that the hal/ini velocity settings are
in machine units (inch in this case)  per second rather the minute

this is my new test file remap_m6:

#!/usr/bin/env python3
from interpreter import INTERP_OK, INTERP_EXECUTE_FINISH, INTERP_ERROR

print(">>> remap_m6.py wird geladen <<<")

def remap_m6(self, **words):
try:
tool_number = words.get('t', 1)
print(f">>> M6 Werkzeugwechsel aufgerufen: T{tool_number} <<<")
# Sofort fertig melden
yield INTERP_EXECUTE_FINISH
except Exception as e:
print("Fehler in remap_m6:", e)
yield INTERP_ERROR

yield INTERP_OK

But this is supposedly not executable?

'remap_m6' is not a Python callable function - 49:REMAP = M6 modalgroup=6 python=remap_m6

I've already made some Python scripts that work, so why is it so different when called with M6?

If I calculate it right, that's >15m/min

I think it's not possible to reach this speed with steppers

The PID setup is missing key values so I would not think you would get
any motion, for example X:

#****************************
# AXIS X JOINT 0 CHANNEL 02
#****************************
setp pid.x.FF1 1
setp pid.x.Pgain 1000
setp pid.x.error-previous-target true
setp pid.x.maxerror 0.000500
net x-index-enable => pid.x.index-enable
net x-enable => pid.x.enable
net x-pos-cmd => pid.x.command
net x-pos-fb => pid.x.feedback
net x-output <= pid.x.output

Always get your machine working fully on axis first, then consider converting to a more modern interface. With say qrdragon, there are quite a lott of additional pins to connect to the GUI to enable every feature but you need to be confident the basics (from axis) are working... Be aware of screen size  limitations. I had to buy another monitor for QTD...

These are the files.  The .INC files were renamed to be .INI so that they could be attached.

I've attached one spindle file:  that one and the one for Spindle1 all work exactly as expected.

I also attached only two of the axis files:  U & Y (due to the file limit).

Can you post your complete hal/ini files, or al least the joint sections of both?

Have you started your config from a terminal to check for errors in the terminal output?

$ linuxcnc


Also some of your remap code looks a bit odd (eg. 'linuxcnc.INTERP_OK)
You might want to have a look at some examples:
github.com/LinuxCNC/linuxcnc/blob/master...rted/python/remap.py

I am at a loss.  I cannot get the stepper motors on my axes to run at the speeds they are set to run.  The axis seems to run at 0.0001 in/sec, not 10 in/sec.

I have them hooked to Stepper Online DM542T drivers, so these are the values in the INI file.
# For the DM542T, these are 5 μs = 5,000 ns
DIRHOLD              = 5000
DIRSETUP             = 5000
# For the DM542T, these are 2.5 μs = 2,500 ns
STEPLEN                = 2500
STEPSPACE            = 2500

The DM542Ts are set to use 6,400 pulses / rev, and the leadscrew moves 8 mm per revolution.  Thusly, I set the STEP_SCALE and ENCODER_SCALE using this calculation
  • STEP_SCALE = 6,400 step/rev  x 1 rev / 8 mm  x  25.4 mm / in 
    • STEP_SCALE = 20,320 steps/in

      For [AXIS_l] 
      TYPE                            = LINEAR
      MAX_VELOCITY         = 10.0

      For [JOINT_#], 
      TYPE                            = LINEAR
      UNITS                          = INCH
      ENCODER_SCALE       = 20320
      STEP_SCALE               = 20320
      MAX_VELOCITY          = 10.0
      STEPGEN_MAXVEL    = 12.50


      Please help me understand what I am missing.

to make the NVME working on the original linuxcnc rpi image,
i need to add this options to /boot/broadcom/cmdline.txt:
nvme_core.default_ps_max_latency_us=0 pcie_aspm=off


cnc@raspberrypi:~$ cat /boot/broadcom/cmdline.txt
console=serial0,115200 console=tty1 root=PARTUUID=a27d77aa-02 rootfstype=ext4 fsck.repair=yes loglevel=5 nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off net.ifnames=0 processor.max_cstate=1 isolcpus=2,3 firmware_class.path=/lib/firmware/updates/brcm rootwait

the 2nd ethernet-port works out of the box (eth1)
i used this for the normal network and eth0 for the FPGA connection:
cnc@raspberrypi:~$ cat /etc/network/interfaces

Hello, yes QtDragon, Linuxcnc is running without any problems. However, as soon as I insert the line REMAP=M6 modalgroup=6 python=atc_toolchange, Linuxcnc starts with a significant delay, then displays the error message "Hard Limits Are Reset To Active!" and I can't even use it. I call this test program with M6:

import linuxcnc
import time

def atc_toolchange(**words):

s = linuxcnc.stat()

if not all(axis.homed for axis in s.axis[:3]): # XYZ
return linuxcnc.INTERP_OK

c = linuxcnc.command()
c.mdi("G53 G0 Z100")

while s.interp_state != linuxcnc.INTERP_IDLE:
s.poll()
time.sleep(0.05)

return linuxcnc.INTERP_OK

Thank you very much for your effort.
