Unchangeable extrusion speed when "Advance" enabled
I have encountered the following phenomenon with both of the latest Repetier FW versions (0.91 Rev.8 and 0.92):
I have recently switched from Azteeg X3 Pro board (ATMEGA 2560) to a RADDS board (ARM). The firmware is running nicely, except a scenario where the advance algorithm is enabled. Whenever I set the linear advance factor in EEPROM to any value other than 0 (i tested from 0.001 to 100), the extrusion speed is always the same. In other words, there is no difference between slow and fast extrusion from the Repetier Host - both buttons produce the same (slow) extrusion rate. However, when advance_l =0, the buttons DO produce different extrusion rates just as it should (in my case 2mm/s and 10mm/s). This is quite annoying, since e.g. the infill is severely underextruded which is usually printed at higher speeds.
Any ideas what could this be?
Thanks for help!
