KRV2000 CNC Conversion

Thanks Benb, I really appreciate your response - it's gone 1:00am here in the UK and I have been trying different things to resolve this all day so I'm now heading for sleep. I will try what you have suggested tommorrow and let you know how I get on. If I cant resolve it with what you suggested, I will start a new thread in the HAL section.

Attached is a file showing the lines that need to be commented out in your matelda001.hal. The green highlighted lines are not configured in your xhc_whb04b_6.hal if you are planning to control the A axis from the pendant you may need to configure this part in matelda001.hal. For know focus on the count pins problem.

I had a look at couple of previous posts about the pendant, looks like you are not the only one pulling hair. The previous model had different pin configuration plus you have the 18 buttons and 16 buttons models and since we are dealing with user space USB driver there might be timing problem that will show up sporadically. Don’t feel bad you are dealing with a pandora box.

Hi Benb,

I've tried hashing out the lines you suggested in the pdf attachment. I get exactly the same result as before. I also tried hashing out all halui lines but that also results in the same behaviour.

I have also tried to use the Marco Gaspar hal,ini and pendant hal files modifying it to try and make it work with my system, however it fails with

emc/task/emctask.cc Flie not open

and

emc/task/emctaskmain.cc Cant initialise interpreter

So, I am missing some files to try his configuration to see how or whether that works.

I am going to start a new thread in the HAL section shortly. Hopefully I can get a resolution.

Thanks for your continuing help - this is becoming a bit of a nightmare.

It looks like you are missing a file, have a look at this link:

A huge thank you to everyone who helped me with the pendant issue, after a long series of advice from Alkabal, I have successfully got encoder counts working. I have still got to do other configuring with the pendant (toolsetter,homing,probe etc) but that can wait for another day because the ballscrerws are due to arrive, so I'm going to be busy machining them.

Many thanks to Benb for suggestions and keeping me going and for pointing me in the direction of the HAL section.

More updates to follow.

Hi Chrissy

Would you mind sharing your setup? Did you ha e to make any configuration changes on the A4 driver? I've got the same setup with the lichuan A4 servo drivers and mesa 7i76. However I have yet to see the servos turn.
