Vertical Line on X Axis

[ak10ng]

I just try using RRF on LPC 17xx and get some problem when XY travel from home to start point, printer get jerk. This is not happen when I'm using Marlin 2. And get vertical line on X axis print.
But when I try rotate print on 90 degree and get better result, Y Axis is normal. No vertical line
This is my config.g:
M569 P0 S0 T1.9:1.9:0.65:0.65 ; physical drive 0 goes backwards using DRV8825 driver timings
M569 P1 S1 T1.9:1.9:0.65:0.65 ; physical drive 1 goes forwards using DRV8825 driver timings
M569 P2 S1 T1.0:1.0:0.2:0.2 ; physical drive 2 goes forwards using A4988 driver timings
M569 P3 S0 T1.0:1.0:0.2:0.2 ; physical drive 3 goes backwards using A4988 driver timings
M584 X0 Y1 Z2 E3 ; set drive mapping
M350 X32 Y32 Z16 E16 I1 ; configure microstepping with interpolation
M92 X160.00 Y160.00 Z400.00 E415 ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E900.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E6000.00 ; set maximum speeds (mm/min)
M201 X1000.00 Y1000.00 Z40.00 E1000.00 ; set accelerations (mm/s^2)
M906 X800 Y800 Z800 E800 I30 ; set motor currents (mA) and motor idle factor in per cent

I'm using BMG direct drive extruder and S3D for slicer with printer speed 80 mm/s.

I'm still search where is the problem. Thanks.

it its at a very specific place, it might be mechanical

since its at both sides at the exact same spot, its a good bet.

[ak10ng]

@Veti if mechanical issue, it can be happen if I use marlin firmware. But no issue if using marlin firmware.
Thanks.

@ak10ng is it happening at layer change points or where there are 'kinks' in the model. If so, I'd say look at pressure advance and retraction. Your RRF one definitely has some bulging at the corners suggesting that you don't have enough pressure advance. https://duet3d.dozuki.com/Wiki/Pressure_advance

Equally, if those are the start/end points for the perimeters/infill, changing retraction will impact. Are you using firmware retraction? And are you using Z-hop?

With both retraction and PA, you may have to double-check your extruder motor settings in case they start limiting the motion (though from a quick glance they look okay).

It's hard to see from your photos, but the marlin one also looks to have some kind of feature at the same locations (though not very clear and could be lighting...). Have you got a link to the part stl?

[ak10ng]

This is my gcode that problem.
led-docking1mmA.gcode
This is for rotate model led-docking1mmV.gcode
And this is my stl led-docking.stl .
I'm not using PA and not using Z hop.
Thanks.

Which build are you using?

[ak10ng]

@jay_s_uk I'm using led-docking1mmA.gcode with problem vertical line.

@ak10ng of LPC RRF.
Post you M122

Have you tried printing the same gcode on version 3.1.1?

[ak10ng]

@jay_s_uk this problem on version 3.1.1, I'm just wanna try using this new FW.

[ak10ng]

Vertical line gone after using FW Ver 3.2-beta3.2_1. Thanks all. And no jerk again from home to start point.
