M906 X1300 Y1300 Z1300 E150: I30 ; set motor currents (mA) and motor idle factor in per cent

Is this what you changed it to? Try this

M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z80.00 E80 ; set steps per mm
M566 X900.00 Y900.00 Z60.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z200.00 E1200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z100.00 E250.00 ; set accelerations (mm/s^2)
M906 X1300 Y1300 Z1300 E1350 I30 ; set motor currents (mA) and motor idle factor in per cent

Also send M98 P"config.g" in the gcode console and copy and paste any error messages here.

@Phaedrux Yes

Did you use the block from me above?

anthonym

@Phaedrux Yes that seems to have fixed it !!

FYI these errors were because you didn’t remove the second E parameter.

M92 X80 Y80 Z80 E420:80 ; set steps per mm
M566 X900 Y900 Z150 E420:150 ; set maximum instantaneous speed changes (mm/min)

You also left the colons : in after the first E parameter value, which may not have helped. And the motor had no torque as you had set it to 150mA:

M906 X1300 Y1300 Z1300 E150: I30 ; set motor currents (mA) and motor idle factor in per cent

@droftarts Its seem to be working , I see that now thank you for explaining I really appreciate the help.

anthonym

so the issue I am having now it’s extruding way too much if I ask for 10mm I get over 100 my steps per mm are 420 on the aero 2.85 mm with a .5 nozzle.

@anthonym send M92 and M350 from the command line and see what they report.

anthonym

@T3P3Tony I will as soon as I get home and post the report. Thank you

@T3P3Tony
Steps/mm: X: 80.000, Y: 80.000, Z: 80.000, E: 420.000

Is your motor a 0.9 degree or 1.8 degree?

T3P3Tony

@anthony1m and you are definitely getting 10x the requested extrusion? Please measure the actual amount extruded when you send G1 E10
