Update: Fixed Laser issue - raise/lower bed controls glitch

#1

@lasertechs @laserusers I’m experiencing a problem with the laser I haven’t seen before - the raise/lower the bed controls are moving the laser along the y-axis instead. The y-axis controls aren’t responding (x works fine). Has anyone come across this before? Restarts aren’t resetting things so laser not useable until solved…

I was on the laser for a few hours this morning and didn’t notice anything wrong with the controls.

The only time I’ve had trouble with the bed is when something has been jammed in there and stopped it moving, old offcuts and whatnot.

But it sounds like it’s something funky with the controls themselves, a bit of an odd one.

All fixed - turns out you hold down raise and lower at the same time to fix

I don’t want to contradict what has been said here too much as I wasn’t there but as some helpful information:

The most likely cause of the Z-axis not moving is that the machine was just turned on, and the safety chain is open or broken. That means you need to close the doors and login to the tool control.

On power up, the laser cutter will try to home all axes; it won’t start until it confirms the safety chain is closed to ensure all safety circuits are working and it can’t cause damage or an injury.

On older machines, like at Makerspace, it only needs a second of a closed safety chain to prove this and will then carry on homing whether the doors/tool control is open/logged out.

Newer machines require the chain is closed throughout the homing process and will fail with an error if you open a door for example - requiring a power cycle.

The up/down arrow being held might be a placebo; this is the shortcut for auto-focus. I don’t know if the Laser Techs train this, we didn’t in the past because it was too easy to have a head crash due to how this older Speedy 300 does autofocus.

Anyway the point is, if this keeps happening, have a look make sure the doors are all shut, that tool control is logged in.

Thanks - good to know. The bottom door hadn’t been closed quite properly on the machine so this does sound like the likely culprit, although the problem persisted after the door was properly closed.
