Status poll of Graphical LCDs and Printing Performance

[Natealus]

I was just curious how other people's experience are with the LCD screens and printer performance?

I've had my delta printer running at 20-80mm/s and 165 delta segments per second very smoothly. But with my Viki 2 Graphics LCD enabled, I have to drop the segments all the way to 38 to achieve smooth printing again.

What are your experiences?

@thinkyhead Alrighty good news. :) After a much more sturdy wiring setup on my probe soldered and heat shrunk, it is reliably working again. It is appearing to work correctly. I've noticed my temps are going a little wonky and triggering heating errors so I'm re-tuning the PIDs.

I've been testing trying to get appropriate nozzle height (at 100 microns). I've been adjusting the M851 z-probe offset setting via console but I'm not certain it is actually moving. When that happened before I found that the change in the firmware and reuploading it was working while the eeprom M851 wasn't actually working. I'm going to test more thoroughly to verify that.

But it looks much more stable and I'm able to put it up to 11 point grid instead of the previous 8 due to compile sanity check errors that were recently fixed. The post-bed leveling movement looks alot more straight but I have to get the nozzle to bed distance right first to be more specific.

The recent servo changes caused some issues getting that working right again. I had to change my AzteegX3Pro_pins.h for the servo from servo0 to servo2 then it was addressable again. Then had to tell the servo section in configuration.h to use servo2 instead. I'm still having an old issue of G29 not extending the z-probe servo and I have to reset the printer before the nozzle hits the bed. But if I use G29 E...it works just fine. Except it extends and retracts the probe for every point. Is that necessary for accuracy or it excessive? I wouldn't think it would move too much probe point to point...maybe it could reset the angle every row perhaps?

Ok after further testing the M851 does seem to be working.

Also another pretty old issue...and I'm not sure if it has come up recently or if it's unique to my setup...but for bed leveling to work right I have to // out the #define Z_RAISE_AFTER_PROBING 50. Or else the probing numbers come out to 100s or 1000s.

But it doesn't affect the manual z homing position like it did before, as it shouldn't. So that's fixed.
