SKR_PRO_V1.1 Marlin 2.0 SKR-PRO LAYER SHIFTING

[luckyscustomleather]

I have installed the SKR-PRO-V1.1 and the TFT35 V3.0 to my Tornado Tevo Printer, managed to get everything working well with the exception of random but constant layer shifting on Y axis.

I have tried modifying the Config files as recommended on various other sites that seem to be having this problem with Marlin 2.0. I have tried to lower the movement speed by 25% And still no changes,

Is there ant issues in my configs, or is this a Marlin 2.0 bug, in which case does anyone have Marlin 1.1.9 for a SKR_PRO_V1.1?

I have attached my Config files, advanced_configuration.h.txt configuation.h.txt

You're using a pretty old Marlin. I would not downgrade to version 1.1.9 I would upgrade to the latest versions.

Hi, I am will try this and see what can be done.

If the Y-axis step is lost, check the current at the Y motor

[radek8]

800mA, that could be OK

Hello Radek8, thank you I have tried this and the same results, what I have done now is buy some TMC2209 steppers and am now trying to configure these in UART. with Sensor less homing for x and y, I am not sure the SKR-Pro-V1.1. supports these yet properly.

[radek8]

TMC22069 drivers are great, I have them too :+1:

[luckyscustomleather]

Are you using them on the skr pro v1.1? If so can you offer some Config settings to get them to work in UART?

[radek8]

No . I have SKRV1.4 You have to have it right.

• fitted jumpers and on the SKR board
• jumpers on 2209 controllers (if not from production)
• Configured Marlin Then it must work

I have a similar problem, the printer seems to change the steps on the axis y and the detail gives more, although from the beginning the printing starts normally.
