Endstop Failures with new firmware


#1

Hi All,

I just upgraded our M200 Plus from FW 1.4.0 to 2.4.2.

The X-axis end-stop switch is now misbehaving after the upgrade (it never did beforehand)

80% of the time it won’t register when the axis homes and produces an Error #203.

We’ve been unable to print after the update (as the printer homes twice before starting a print)

Any advice would be good!

Hi @blah!

I guess you mean the error 5:5.

Have you gone through the axes check procedure? Please do so. If there is anything wrong, you’ll receive information on the screen.

Btw. Does the extruder hit the frame in the corner or just the enstop does not recognize the contact?

Kind regards,

Marcin Rańczuch

I can’t complete the axis check as the printer needs to home before completing the check.
The Y-limit switch is now also not working.

I have used a multimeter to verify the action of both switches (X & Y), both function electrically and mechanically as expected.

I have also updated the printer to SW V2.4.3

Here is a video of the printer failing its Y-axis homing sequence, you can hear the limit switch actuating.

I have also completed axis maintenance as described here:

This all started with a firmware update - it really feels like a software problem

Hi,

Just following up to see if the Zortax team have any more suggestions, at the moment our printer is unusable and costing us money in external print fees.

Cheers,

Hello,

I am sorry to hear the problem has not been solved. Please, contact us via support form so one of our support agents can provide further help. Also, please attach some videos as the file you uploaded cannot be displayed. Also, please check the extruder’s motion, as shown in step 3. Still - it is rather unlikely that the software/firmware is causing the issues, especially that you already upgraded from 2.4.2 to 2.4.3 and the problem persists.

Best regards,
Karolina
