@Fisher said in Another mirrored core xy question:

M574 Y1 S2

i made a mistake in my op but cant edit it as its getting flagged as spam for some reason i am changing
** M574 Y2 S1 **

solved: incorectly wired endstops... i knew it would be somthing silly, thanks all the same.

Im currently commisioning my new printer, all movemnts seem to working corectly except the y axis is mirrored.

This image shows how i want the movemet configured as well as the location of the end stops.

my current config (i have removed non relevent sections):

i belive i have to hange the following :

• M669 y-1
• M574 Y1 S2
• change the movments in homeall and homey to positive movments

ive tried this and the movment directions seem correct but i get strange behavior when homing where the x axis tries to continue moving beyond the end stop limit.

Am i making the correct changes or am i missing somthing, TIA.

@Veti Would you be able to explain a little more about whats wrong with this or point me towards some info on thermister settings / what is a beta value? my hotend thermistor is a generic one from e3d, my bed thermister is integrated into silicone heat mat - cheap chinese one doubut i'll be able to find any documentation for it.

All sorted Thanks once again.

@dc42 thanks, i will still need to amend my endstop location and homeall / homey directions i assume.

@Veti Ok thanks, im going to get the basics sorted before i try and understand what a beta value is.

@Veti Thanks for pointing that out, idk why i had it like that, here is the full config:

@Phaedrux Thats very gracious of you, thank you very much.

@jay_s_uk Thanks, Can anyone give me some guidence on how i would set up one of the heater pins on the expantion header to control the SSR?

@Phaedrux Unfortunatly i dont have a picure of how it was before, i noticed the problem by moving the header and seeing that the pin on the back was also moving. E1 is currently open but i did plan to add a second extruder in the future. would it be possible to use a couple of the pins on the expansion header to drive the SSR?
