Mach4 General Discussion / Drive stepper continuously on M07
« on: July 12, 2023, 06:04:14 AM »
Hi,
I’m using MACH4 with a PoKeys57CNC board and trying to set up a stepper motor as a pump to feed my mist cooling system.
I need to get the stepper, connected as Motor3, to run continuously on the M07 command but can’t see a way to do this directly without using an external motor controller triggered from an output.

Anyone know if this is possible?

Thanks.
DerekJ

Then try dropping Tech Support a line from the support pages on the main web site.

Sorry it did not work for you. Mine works well now once I got over the basic learning hurdle.

Cheers

HI,

SRO is Spindle Rate Offset not Spindle speed.
Use something like G0 S1000 to drive the spindle to 1000rpm then use the SRO slider to trim the speed.

Hope this helps.

LOL :-)

Before I retired, I spent 15 years as a programmer.
It's hard to explain to someone why you have worked your donkey* off for a week and only produced 5 lines of working code. Most people don't see the 100 pages of abandoned code-tests and dead-ends.
BUT the WORST, the ABSOLUTE WORST, is to spend days trying to debug some code, only to find an obscure reference on the Internet that says "this behaviour is by design".  So I know how you feel. :-)

Best
Derek

* donkey.... a kind of ass :-)

Hi Brian,

Works for me!  :)
I replaced the entire FontEngrave folder in C:\Mach4Hobby\Modules\AddOns with the contents of your ZIP.

Below are the Gcodes collected in the same way as my previous post.
You can see that the X position is the same in both so enjoy that drink!

Thanks again
Derek

OK thanks, don't rush for me if you have more important stuff to do.

Just so long as I didn't miss a download link or something in the previous post.

Hi Brian.

Did you solve this issue? Is there a LUA file to download?

Sorry for spoiling your Sunday.

Hi Brian,

How did the snowmobile outing go?
My cake was Soooo Gooood   :-* Chocolate sponge with black cherry Jam (jelly?) mixed with cherry brandy as a filling.

Anyway serious stuff...
I replaced mcFPanel.lua in C:\Mach4Hobby\Modules\AddOns\FontEngraving with the module you gave me to download.
Started Mach4 and selected Simulation Device as the motion Device as I'm not at my CNC at the moment.
Restarted Mach4
I did not bother with zeroing the machine etc.
Opened "Select Wizard\FontEngrave"
Don't change anything, just hit "Save and load"
Point to a save file to save it in
this is the start of the Gcode that was loaded...

G0 X0 Y0
S10000 M3
G00 Z1.0000 M8
X-39.5300 Y55.0150
Z0.2500

Close the Gcode file
Just repeat the above procedure to get this Gcode.

G0 X0 Y0

G00 Z1.0000 M8

Z0.2500

The difference in the first X position is 326.24.
My soft X limit is 320 so the second shot at engraving is almost in the same position just one bed size over.

I'm not in any kind of rush to get this resolved so enjoy whatever is left of your weekend with the kids. :-)

Thanks for the support over a weekend!
DerekJ

P.S.
I tried to attach some cake for you but it made a mess on my computer keyboard when I tried to push it in :-(

P.P.S.
Should have said that the two lua files are the same size ((443,511 bytes)

Thanks Brian,

I'll try that later on when I get my machine back on line.  Baking a cake at the moment :-)  How random is that!

Thanks for the help

Hi Brian,

Yes, the original top few lines of Gcode in my original post were made like this:-

1)   Exit Mach4
2)   Start Mach4
3)   Home the machine
4)   Move to centre of bed
5)   Zero work coords
6)   Enter the FontEngrave wizard, all values saved from last time including text start X & Y.
7)   Press Save and Load, copy the Gcode to post here.
8)   Close Gcode File
9)   Enter the FontEngrave wizard, all values saved from last time including text start X & Y.
10) Press Save and Load , copy the Gcode to post here

Please note that I'm very new to Mach4 and CNC in general so it's probable I'm doing something stupid!
