Stepper Motor Speed is too slow

Category: Basic Configuration

10 in/sec is well beyond what we ever need; indeed, I'd be surprised if we need to achieve even 0.1 in/sec.  That was just an attempt to see if changing that value would drive the needed speed.

As for commenting out the PID stuff, that was due to the way I understood them to be only needed for servo motors, and not for stepper motors.  This is based on my reading of section 2.13.2. Servos in the manual (linuxcnc.org/docs/stable/html/config/ini...ub:ini:sec:joint-num).

Quite probably, I misunderstood the manual.

I will add the PID stuff back into the configuration and test tomorrow, and then report back.

After looking at the schematics and hal file I realized there is an error on one or the other but the estop pin I needed to get the machine to release was on tb2 rather than tb3 that the drawing indicates. I connected that so it is "bypassing" the non existent estop switch and bobs your uncle I can get the ui out of estop and mess around with pin outs and what not. I plan on editing the program quite a bit more to move all of the user controls to the 7i73 that will be mounted in the user interface box rather than running all the wires back to the main 7i77 in the electrical enclosure. I verified connectivity with the 7i73 so it should be fairly smooth sailing from here(crossing my fingers) I have ordered as many different breakout boards/connectors so I don't have to splice into the existing wiring. My goal is to have as minimal invasivity if that's a word as possible. In theory being totally reversible with no retermination of connectors. It added a bunch of extra cost but I think it is way more valuable having all the connections in tact and original.

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:

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.
