Runs Extruder Backwards !?!?

txkevintxkevin
in Repetier-Server
I am running Repetier Server on Windows connected to an Ender 3.  I am trying to adjust the Estep (with some difficulty due to slippage) so I using the Extruder Controls and changing the Estep values in Console.  When I go to Control and Extrude and with great care, assure I depress the down extrude button, it sometimes extrudes and sometimes retracts...for a long long time.  WTF?  How do I assure depressing Extrude in the Control Panel does not somehow retract.  Also how do I freaking stop it from retracting?  It will retract until the filament is completely out and continue..until i curse and turn it off.  Any suggestions would be appreciated.

    Please do this in the console with commands enabled. Then you see the commands being send compared to what you wanted and it should be easy to see what is happening. Server does some assumptions on the extruder mode (relative or absolute) and also assumes to know the extruder position from previous moves. So make sure no other software is controlling the printers e move like printing from sd card, manual menu moves. Server will not see that and send coordinates that are not correct any more.

    Once you have the command send compared to your action you can post it here with comments next to commands on the action you did and what really happened.

    You can interrupt long action sin firmware only be sending emergency stop if this causes a printer reset (some printers do not do that).

    here is the code.  I ran a few tests that worked fine.  last one selected Extrude (down arrow) on Rep Server 2 mm / sec and 10 mm distance.  It ran RETRACT for about 20 seconds until I turned the unit off and pulled the USB to stop it.  No consistency on the EXTRUDE control panel at all.

    I see big gaps between the commands. Hopefully these are only temperature requests. Regarding moves I see only this
    13:56:53.752: N1165 G1 E350.00 F600
    13:56:53.752: N1166 G1 E400.00 F600
    13:57:53.253: N1226 G1 E450.00 F600
    13:57:53.253: N1227 G1 E500.00 F600
    That are 4 moves a 50mm extruding. No reason to go back. No idea why it started with 350 might be in the 150 lines missing.

    I assume the retract happened with the last move as you resettet printer after that. But that command is correct and does the same as the previous 3 previous move.
