Spindle clamp down sensor alarm12/24
I have an Omnitech Selexx Mate cnc router. During a tool change, I got a spindle tool clamp down sensor alarm. I shut the air off and released the hose to the carousel and was able to push the carousel back but the tool is stuck in the spindle. The tool release button on the side of the spindle doesn't do anything. I have used the E-stop and rebooted everything a few times to no avail. Just before this happened the spindle dropped a tool out of the spindle so something is screwed up.
Anyone have any ideas how to fix this? I can't get to the sensor at this point because it is buried back inside the spindle somewhere.
I should also note that nothing bad ever happens during the week- only on Friday afternoons or just before a holiday when everyone at Tech Support has gone home!

Do you know or can you look up the code (perhaps an "m" code) for the unclamp action? You could try entering that by itself to see if it forces a release.
I'm thinking that the unclamp sequences uses a series of codes to complete the action. It could be possible the unclamp sequence is getting stopped before it ever gets to the unclamp code line.
That is how things are set up on my CNT Motion router with a HSD spindle.
A totally wild shot in the dark here but perhaps worth checking out.
I have an omnitech spectra. I had the same thing happen about a month ago. It turned out the machine wasn't completely clamping the tool holder into the taper and causing the alarm. I couldn't get the tool holder out as well and through a series of different attempts ending up telling the machine to change the tool. It was able to get the tool out but it was loud and I don't know if I'd recommend it. Once the tool was out I just cleaned everything really well with wd40 and had it do a bunch of tool changes and everything was back to normal. Prior to that tech support had me take out the sensor on the spindle and test it. It was working so they thought it just needed to be adjusted. I adjusted and ran the machine and had a horrible vibrating noise. That is how I discovered that the tool wasn't clamped in completely. You can also open the cover on the machine and manually activate the solenoid that controls the clamping of the tool to try to release it that way. It didn't work for me though because the clamp was actually stuck.
We used to run into this daily where the plc would tell us it hit a time out in a tool change. One day we tried to manually releade the tool holder and had to use a hammer. Looking at it we discovered it was filthy and had the consistency of a rusted item-with no surface rust.
We set up a maintanence program that has taken care of this problem for us. We run about 10 hours a day with multiple tool changes. We clean all the tool holders with alcohl and the spray them with Lusin. We spray one with a liberal amount and work it in to the spindle.
We run this program every Monday morning and check it off as we go. We also clean filters, check fluids, grease all nipples, blow the machine down, check the collector fittings and inspect the chain. We aslo make sure the FRL is using the proper amount hydralic fluid
I hope this helps
cabinet maker is right.
There is most likely a build up of "Crud" on your tool holder that is preventing a smooth release of the tool. Using a rubber mallet to release the tool and then ensuring everything is clean should correct the problem. Of course monitoring this and preventing it in the future is key.
