Don't use T0101 format unless you have set up linuxcnc specifically that way. with tool change remap code.
G43 is required in linuxcnc - again unless you have specifically set it up to hide it's use...

You can't add the fonts in glade nor can you set the theme ( I picked a dark theme)...this is what that same panel looks like in glade.
This must be done with Gscreen - which uses a python...

so in this pic the main DRO uses Bravenewera font, machine DRO uses transistor font.
I agree the Gcode colors aren't well suited to the black theme..thats a separate file to work on later....

It was done with GLADE editor and Gscreen program included with linuxcnc.
The large DRO actually uses a different font the the rest.
Want font did you use? I couldn't find a font close to yours on...

So I tried to make a screen for linuxcnc similar to what you displayed....
It still needs some detail work, but the concept seems pretty good....

Do you have any parts for these machines that you are interested in selling?
I have an old lh35-n osp2200 and am looking for the splined flange adapter on the back of the spindle.

It would make more sense to use spindle-at-speed - something like above:

I have smartcam version 7.55 turning.
It originally ran in dos but I run it in win95/98 - it uses a parport dongle.

I am interested in other products of about that era, particularly advanced...

You should use gladeVCP for in panel input to MDI commands.

The 5i25 comes pre flashed with a firmware.
This is the firmware you must select in PNCconf.
leave the smartserial box at what it says - the 7i76 requires a smartserial channel for it's self....

But that's not the actual problem.

Can you use a compensation file? from the manual:



COMP_FILE = file.extension - A file holding compensation structure for the axis. The file could be named xscrew.comp, for example, for the X...

I would turn switch 4 off so full current all the time.

look here for ideas of other drives:

having too large timing numbers limits your top speed.
Too low can lead to missed steps or non functioning...

You may have been thinking of ncbox.

I know nothing about it - just heard of it today.

I believe this is up/down mode in linuxcnc.
look for step_type (under parameter heading) here:
Mesa HostMot2 Driver

It's step type 1


Chris M

we now recommend:
1500 step
2500 space
dir 700
hold 700

A bit more conservative but still allows more speed then most can use.

There is a way to set up axis to 'filter' the gcode in anyway you want programically.
I'm betting having it look for M3 and adding a dwell command just before it would not be much trouble other then...

hmm I don't see anything obvious yet.
You are using a classicladder estop option and you didn't include other config files so i can't check them.

when you are running linuxcnc open a halmeter and...

post your config files.

I have used an op amp to create a voltage to run a servo for testing, using the parallel port.
It would surely work for spindle control. The resolution of the voltage is not that good with the...

motion.feed-hold - (bit, in) When Feed Stop Control is enabled with M53 P1, and this bit is TRUE, the feed rate is set to 0.

so if m53 is set then linuxcnc will...

It is not supported in any released version.
I don't know about a developer version.
You should ask on the linuxcnc maillist or linuxcnc forum.

The first one yes. motion.feed-hold pin
The second one probably not. are you meaning to go back 50 steps of gcode ?

Ask on the Linuxcnc maillist or forum.

Max velocity is set in the INI file.

Is 60 inches a minute the machine's limit or just the setting for AXIS?

obviously you don't want to go faster then the machine's limit!

You don't give much info.
either change the physical wiring or change the HAL file 'wiring'.

well why don't you try a lower max velocity and a lower acceleration?
see if that works better!

could be drive timing numbers are too fast. What step driver are you using?

could be cross talk...

Well do you have some sort of feedback from the spindle?
some VFD's have a stopped signal,
of course an encoder on the spindle
or a timer set to wait the longest it would ever take.
