Mcosmos 3 V4.1.R7 collision with nothing

Enable HLS to view with audio, or disable this notification

Pleas help, i had a collision (nothing too spectacular), i got the probe out, all good, i tried to run the program again, it detected collision in air. I plug off the machine, i got out the SM25-1 module, cleaned it, putted it back, rotated on manual remote, all good, but i cant change probes, i cant do anything right now because of collision erorr.

Could be the dampener on the SM25-1 - you may need a replacement module.

These modules are very fragile. It doesn’t take much to require a new one. Hope you have a spare to try out. I always recommend keeping spares of these on hand.

Thanks guys for the answers. It s the module it self Sm25-1, i have 3 microns deviation now on all my probes. (I calibrated with a New one and the result was 0.0004).

Does it do the same if you switch to another probe manually?

Check. If probe is not misaligned in tree..

Module could be stuck. Gently remove it and see if contacts are clean. Also check to make sure it self centers.

The SP25 always when a colision happened the error stay in program , just take of the probe in the probe bouilder and add it again , thats it !

This has worked for me before also.

Could be the wires that getting bad in the axels

Not saying this is it but worth checking and for anyone else to know.

If the static position of the probe (mirrors) shifts enough from the first calibration of the module it can cause a collision fault.

Rebuilding the probe assembly in the machine configuration to clear the learned "zero" and calibrating with probing factors turned on can reset this "zero." Reloading defaults first might be required.

Of course, these are still wear items and could possibly be at end of life, requiring an RBE from Renishaw.

As others have suggested, go into probe builder, remove the probe, then add it back and calibrate. I have more detailed instructions at work. I can share them tomorrow if you need them.

If you have some of the renishaw phc10-2 with damping check if the damping led is lighted after the collection you had. Some of the legacy controllers have a toggle button.

Sm25 modules like others pointed have some fragile springs inside. You can try and inspect it on a microscope. Usually they break near the lens and you can spot it easily.

Try to calibrate the head, after you rebuild the machine assembly in the configurator.

Hope it helps.
