I've been using EMC2 (V2.3.0) on Hardy Heron for some years and it works very well. For some unknown reason yesterday, when starting it gave an error report with loads of lines saying "waiting for s.axis". I rebooted the machine and all seemed well.

When I tried it again later, it gave the same message again and I could not get it to start. I thought it was probably worth upgrading so I followed the instructions to upgrade to version 2.4.8 however when starting it gave a similar message. I therefore upgraded to 2.5.0 however it still gives a similar message (see below).

I have not changed any of the settings for months so have no idea why it is suddenly gone wrong. Any suggestions appreciated... I only have X,Y and Z configured and it's worked for years.

Details of error report:

Do you have a joypad for jogging? I think I have seen this problem when the USB plug came out.

Hmmm - not exactly - I have a home made pad with a rotary encoder and a couple of rotary switches. These are fed into a second parallel port. I could post details from the config file but first I better check out the wiring in case something has broken. Thanks for the suggestion.

These are fed into a second parallel port. If it's on a parport, then that isn't the problem. Dodgy USB stops the hal_input module from loading.

Thanks Andy,

I'm just back from checking out the parallel port leads - shells off the D types and wires all check out ok. I put them back on then commented out all Parport1 stuff (jog wheel inputs) in the config file - the machine worked - great I thought - on to something. I therefore removed the comments so I was back to normal and strangely it still loads and works ok.

I'm not sure what the problem was but for now at least it has gone away - not ideal since it will probably come back but we shall see.

Thanks for your suggestion anyway - oh and to answer your question, yes I has tried the other front ends instead of Axis and all gave the same problem.

All the best
Martin

Hi, thanks for the suggestion.

When I was upgrading, I followed the upgrade instructions to the letter and definitely did comment that out in the configuration file.
