Need Help Gerber Sabre 408 issues

[signfabshop]

Hello, I have been working with a Gerber Sabre 408 flatbed router for a few years and I have a new issue I can't seem to solve on my own. We recently had to get a new computer and router motor. the software is the Artpath 7.0 the new router motor is a Bora. This is our second Bora head the first one broke within a year. The issue is when I send a file to route it will route fine one time. The next time I try and send a file it will send over to the router and it will act like it wants to route but the motor doesn't spin. It will go down and start to move across the x and y axis but never starts to spin. My only work around now is to let the machine sit idle for about a hour or so and try again. Sometimes it works sometimes it doesn't. I've let it sit idle with the machine still on and it seems to take longer to "reset" or cool down or what ever it needs to do than when I turn it off to let it "reset".

Couple questions?

Have you updated the spindle drive software since the upgrade.

Is the spindle chilled? If so, have you confirmed you are getting flow?

It sounds like the drive is going in to an error state. Depending on the drive you may be able to monitor your screen or plug straight into the drive and check for error states.

I have had that happen before, I alway shutdown everything, computer and router. Sometimes I will scan the computer before restarting the router and it usually clears it up. make sure you are sending out to rout and not accidently hitting plot because if you hit plot instead of rout it will go though the motions but not spin.
hope this helps.

It sounds like you are using a 120VAC router and not the "high frequency" spindle that uses a separate VFD electrical cabinet to run it. If so, then it's a 24VDC contactor that switches the outlet. The motherboard has an output providing +24VDC and a switched 0VDC (to complete the circuit), you need to verify that the 0VDC pin is switching correctly... I attached a photo circling the connector and showing the +/- pins. When activated, there should be a 24VDC difference because the left pin is +24VDC and the right pin is 0VDC, when deactivated no voltage as both are +24VDC (left directly connected, right being pulled up through the relay's coil that has no current flowing).

Let me know what you find out!
