Excitech 1212 Setup HELP!!!

[SEALvet2]

I’m “Looking” for some HELP setting up an Excitech SHG-1212 router machine & V Carvepro software.
I am under the assumption that an output file from Vectric Vcarve Pro should run according to the tool database settings within the program.

Using the correct output perimeter of mm’s the 1212 defaults to machine speed and feeds (way to fast) when running the U Disk file. I am missing something in the DMO machine setup that allows the U file to run according to the Vcarve Pro software.

I live in Southern Ca. Trying to find someone I can talk to that has both an Excitech machine with Digital readout and VcarvePro. I read the manual but still missing something!!!

Yes…….I am new and lost in the world of CNC…..BUT excited about learning!

G`day SEAL, Our software is set for " G -Code arcs mm ", however as you are probably still using imperial sizing is there a G -Code arcs inches setting?
If in doubt hop onto the vectric forum and ask the question. I am at home and do not have V Carve Pro on this computer.

G`day to you rocket67,
THANKS for the reply
My question is on "Setting up a Excitech DMO Digital readout connected to their router machine"!
No problem with your software or outputting file, just can't get the machine to "SLOW DOWN" when running a file on U disk!

I don't think that the DSP always (if at all ) recognises the speed commands in the G-code. I set the speed of cut on the DSP anyhow.

I have only had a short play on one of those Excitech DSP pendant thigies.

But as I remember there is a parameter on it you can set to make it take feed rates from gcode.

If this is not set then it takes no notice of the feedrates in the gcode and uses whatever feedrates are set on the pendant.

Also I believe, there is no way to make it set spindle speed from gcode. That must be set manually on the VFD.

Thank you Greolt and Big S for your reply
New Info in from Excitech I received today:


"It is easy to setup the machine to run the file from the U Disk at the speeds from the Ucancam file.
Please go to
Menu--AUTO PRO SETUP--G code Read Setup--F Read, Enable.
Done.
Best Regards
Ronny”

If this works I will have to find out how to adjust the VFD for the spindle speed....I am pretty sure mine is running at max of 24,000 rpm. I am a little hesitant of messing it up, anyone got a quick answer on VFD adjustment?

[Greolt]

Yeah that's about what I remember.

The VFD will either have a knob to turn, or up and down arrows. Just have a try you won't hurt it.

UPDATE:

Well it appears that there must be "Another Magic Key" needed to make the DSP recognize U file tool speeds and feeds:

"It is easy to setup the machine to run the file from the U Disk at the speeds from the Ucancam file. Please go to
Menu--AUTO PRO SETUP--G code Read Setup--F Read, Enable".....

DOESN'T WORK

[Greolt]

When you say it does not work do you mean it is still taking no notice of the F commands in the gcode?

Does the gcode you are using have F commands in it? I ask this because the gcode sample that was given with the machine I used had no F commands.

Perhaps the software that comes with it (ucancam??) does not issue F commands in the gcode it produces.

If you are not sure then try running this gcode,

G1 X100 F500
G1 X200 F100
G1 X300 F1000

Or if using imperial,

G1 X4 F20
G1 X8 F4
G1 X12 F40

Greg,

it is still taking no notice of the F commands in the gcode?

.....Correct!

I think I am "Mudding up the waters".

When I initially contacted the gentleman from China, Ronny, I told him I was using the Ucancam software so as not to complicate the issue or question. Actually I am focusing my efforts on the VCarve Pro software that I read is being used by many others on this site. Ronny stated: [QUOTE]Menu--AUTO PRO SETUP--G code Read Setup--F Read, Enable"[/QUOTE]
This has proved Unsuccessful!
The machine appears to be well made but without a user manual......I'm shooting in the dark for answers!

I do not know if the VCarve Pro software I am using using has F commands in it. I will try to run your sample G code but as I noted early on my knowledge in the CNC world is quite limited.

Thank you for your assistance!!!!!!!!!!!!

Sir (I dont know your name),

I had the same problem with some of the Excitech systems we dealt with. The resolution may depend on which version of their DSP controller you have. What I call the "old" version, which is the first one I used, would never pay attention to F speeds. I had to set the speeds from within the ZHBUSBCONNECT.exe program, then Re-send the file to the handheld each time I wanted to change the cut speed.

The later version of the handheld paid attention to the F commands, I believe, Once I set the setting you were talking about earlier. I believe I have one of those handhelds in storage, as well. If need be, I might can dig it up and see what I can figure out.

Why don't you create a Gcode file of cutting a simple rectangle or circles and send a copy of the G-code for me to look at. Also, send a photo of your handheld along with a model number if you have it. Maybe I can help.

So forgive me for butting in.

As i understand it - you need to know how to alter your spindle speed. We do not know how to do this within a program, however here is a good explanation of how to alter spindle speed through the inverter. This was written by Shannon ( Big S ) when i put a similar question to him in an Email -

The inverter keypad is quite simple once you know how to adjust the speed. If you push the mode button it toggles through the display settings and then after 5 or 6 settings it returns to theoriginal display. On one of the settings there will be the 0 at the right of the display flashing. If you then use the across arrow button till it gets the first digit flashing, you can change it with the up and down arrows ( you can change any of the digits to set the output speed ).
If it is on 400 ( hz ) that would mean an output rpm of 24,000 for a 2 pole spindle. Shannon has been warming his spindle up each time he uses it by starting it for 2 minutes on 200hz ( 12,000 rpm ) and then 2 minutes on 300hz ( 18,000 rpm ). If he is going to use the spindle at 24,000rpm he will warm it up at that speed also, but he mostly uses it at 18,000 rpm.

Thanks Shannon - hope you don`t mind me pinching your written work.
For SEALvet2 - It should answer his question and get him cutting.
