A couple weeks ago I started a carve on my 40-913 . I left it unattended and went back in the house. After about an hour I went to check on the progress and the bit had traveled back and fore and down the plaque about a inch or so......the motion had stopped and I had a Error Code #12 (Spindle Motor Overheat). I wasn't feeling real well so I shut everything down and went back into the house. Today I went out to the shop to try again. Set up the carve and ran the Border Inspection. Toward the end of the inspection (twice) I got Error Code #12. The spindle motor doesn't run during the inspection! Any suggestions?

FatPoppy, You might try this procedure in the attached photo to verify that your spindle will run and stay on without kicking off and throwing an error code. My spindle motor does not run when doing the border inspection, it only comes on once I select the carving speed of Slow, Medium or Fast. If your motor will not run and or stay on with the procedure you might want to check the connections behind the spindle motor cover. I would disconnect them and reconnect just make sure that you only pull on the connectors and not the wires. Also check to see if all the wires leading into the connectors are pushed inward toward the connectors and lastly make sure your green ground wire is connected properly

Just like the computer systems on cars, the error codes will only get you in the zone where the problem is you then have to locate the exact cause from there.
I would start by pulling the back cover on the boards and making sure everything is clean and fans work you may have an overheating driver board.

Thank you guys for your input.
I've still had no luck with this problem. I am conversing with Jeremy at Iconic also.
What I've done:
Spindle Motor's cover is loose so it can get more air. Rear cover is removed also. Blew small amount of dust out of covers.
Replaced Spindle Motor with new spare motor. Checked wires.
Let motor run fifteen minutes. Ran smooth, was warm but I don't know how hot it should be.
I've asked it to PARK or HOME several times and it has done what it should every time.
Fan on back cover works.
I have noticed that when doing the border inspection, at first it would get about 75% around before the error code. Sometimes now it about 25%. I checked it a few minutes ago and it was at about 60%.
I'm going to visit our Grands in New Orleans tomorrow morning and be back mid week. Maybe it will fix it's self while I'm gone.
Thanks Y'all,
FatPoppy

Does it do it on any file?
This may get too far into what you want to do but I would also check any transistors with a heat sink the sink uses a special white grease designed to transfer heat after years it can dry out and then it will act as a gasket instead of helping the transfer of heat.
Other things to check try another usb drive, oil the tracks worm gear and guides, make sure you are not binding in movement. Did you do adjustments to the machine before this happened?

Since the spindle motor is not spinning while doing the border inspection, I'd suspect it might have more to do with the overall motion of the gantry vs. the spindle motor itself (I know, it doesn't make sense with a code saying spindle motor overheat). I'd adjust the table to insure it's "square", oil the tracks worm gear and guides (left to right, up/down). Then manually run it fully in the x,y,z modes to spread the oil evenly before running another inspection circuit.

Thanks for the replies Greg and Rick, I got back from N.O. (second trip) last night. I hope to be able to get out in the shop tomorrow and put the old motor back on (need to save the new one), oil, adjust and clean the machine as you suggested. I also want to try to run a different border inspection from a previous carve that is still on the memory stick to rule out the G code where the problem started.
Thanks,
FatPoppy

I did remove the new motor and reinstalled the old one, do the oiling, adjusting and cleaning and reran the border inspection on a old g-code that I had carved with no problem a couple of months ago.......still got the error code 12. I have been conversing with Jeremy at Iconic CNC and he thinks that it is the spindle board giving the problem. I put a new mother board in a year or so ago and this would be another $369. I'm not sure if I'm willing to do that on this old machine.
I had considered a X-Carve but have decided against it. I'm now thinking very hard about a Shapeoko XXL. It has about a 33" X 33" cutting area for about $2k. For what little carving that I do, I think that it may work for me. Will just have to decide.

What software does the Shapeoko run? I'm so used to ipicture and grayscales that I can't see learning something complicated at my old age. I am considering a Iconic machine strictly because I'm too old to learn new tricks.

I think Shapeoko's company name is Carbide3D. Their software is Carbide Create. It's free to anyone that wants to download and use. I have played with it a little and so far I think it doable, but I could be wrong........I'm most likely older than you and I'm hoping that this old dog can still learn a few more new tricks also. I had been told by Greg that he uses Cut2D Desktop and Photo VCarve on our machines and they seem doable also. That's what I had planned to switch to. I still may use it if the Carbide Create doesn't work out.......all this is just hot air for right now, I'm having some circulatory problems and had the right leg worked on in August. The left one is scheduled for October 28th and everything depends on that outcome. Getting old is hell.

It is possible to remove all the boards and run a www.geckodrive.com/ and control it from a pc with Mach3. Talking about design software it all creates Gcode and if you use the post-processor file made for this machine it will all work. I have built and rebuilt many circuit boards a good technician in your area should be able to spot the problem. You could start by checking both sides of the board for burnt or hot spots. |

Thanks Greg
I'll see if I can find a board repairer in the Mobile/Pensacola area.
Thanks again,
FatPoppy

It would help a little if you could pin down witch drive is failing like does it do it in the same direction every time?
is it X Y or Z?
Most of those drives only handle about 2.5 amps anymore than that and you can blow the driver board so it doesn't take much drag to overload the driver.
