Remora for RP2040

Ok, code and repo updated with a simple #define for when compiling for the PicoBOB.

Just to give an update on the design. We have found that we get disconnects (lose ping) between the W5500 and the RP2040 after running for around 4-6 hours. Don't currently have access to a way to debug this in detail, but it looks so far like it might be that the IRQ line needs an additional pullup.

Hi Scott,

i have tested the code and get joint following errors. i have tested it with a PI4 (original Linuxcnc image) and a notebook. it happends with fast feedrates very often ,but also with very low feedrates. Board is the W5500-EVB-Pico.
with halshow the cmd and fb values are the same. i also tried twice of the servoperiod.
i used default config without uploading , the rest is from the PicoBOB
I'm grateful for every tip to limit the error.

if i find later time , i will try to upload a config with only one stepgen/axes.

Hi, can you please share your hal and ini files so I can have a look at your config?

Hi,
attached my Hal and ini. most default from the PicoBob sample.

 

Hi,my error comes that ferror limits are reached. settings of the screenshot are MIN_FERROR = 0.5are these rounding issues ? or is min_Ferror = 0.5 to low ? i added also halscope.csv renamed to .txt
