After commenting out " || (dx - moveL <= dlen2)", the scope looks like this.

My apologize ...
sorry I can not show same speed test because I am currently weeks out of office but we can just multiply or devide values ... because it is linear dependecy during constant speed movemet ... 

I can just customize current images to show exact difference ...  compensation off ferror = 0.125mm at 15m/min ...  compensation on ferror = 0.00009028mm at 1m/min and multiply it by 15 we get 0,0013542mm which is significantly less then 0.125 ..

What I remember from testing by my short eyes it whas something near 0.001mm during that 15m/min testing was done with bentch top setup without any load presented... just AX5106 with AM8xxx motor 

but I can go home for testing this weekend to create exact speed difference testing if it is neccessary

No apologies needed [img]/media/kunena/emoticons/wink.png[/img]
 

I can understand You and YangYang, its added job, but I openly disagree ... its the best time to improve lcnc and solve it at native level for ever, no other proforma hobby solution as now my is...

it should be solution for everyone who not understand it soo well as you guys... my solution of compensation will be even more inaccurate when scurve will be done and implemented ... 

I can not say you what to do, your job, your rules, your output ... thanks for your upgrade to curving
