hbot homes correctly but prints mirrored ,

@peter247
so which lines do i change to to reverse the direction it homes ?

peter247

So does your machine home to the left or right , front or back.
I think I may be wrong what is the first few line of M122

M92 X200.00 Y200.00 Z800.00 E138.2316760023409 ; set steps per mm

are you sure your extruder shouldn't be E138.2316760023408 step per mm , never seen anyone set the Esteps to 13 digits before.

tracar

@peter247

i posted some photos of the setup. it homes to the left side, and to the back.

as for the 13 digits, lol.... old habit just a cut and paste, cant be too accurate hahahaha

where is the M122 located

peter247

@tracar

where is the M122 located ? top of the screen !!!
Type M122 in the send code box and click send and post the first few line in the console .

I think I know what happening again ... new idea !!!!!

You have used the version 3 configurator , but you have not upgraded to firmware version 3 and still on version 2 .

what are the 4 control boxes at the back ?

tracar

@peter247
the 4 black boxes are closed loop drivers for the 4 steppers x,y,z1,z2
i will get back to you on the above when i get home

peter247

@tracar

This time I think I'm correct , because after looking at your config.g and homing file I could not find a fault.

Your machine looks a bit of a beast !!!
I tried to making my own version of the cr10 and over killed it to the point where it just printed so bad , In the end just got a ender 5 plus.

closed loop drivers ? , do you just connect the wire which was going to the steppers are use external drivers ?.

tracar

@peter247
closed loop drivers are the ones for steppers with encoders built in.
the steppers wont skip and loose track of their position even if you push an axis out of position. it will self correct....., its all good but if the belt skips then it will loose position. really good for systems with ball sxrews.

@tracar said in hbot homes correctly but prints mirrored ,:

y+ will move the head towards

Your Y axis is flipped. +Y should go to the back. -Y to the front. This places 0,0 in the front left corner.

See this post on what you must set based on your physical printer and then what you need to change to make that work.

I think he is using the version 3 config.g and still on firmware version 2 , so I think it just ignores parts of the config file and works in a default way.

Yup you're totally right.

Phaedrux

To update to RRF3 you need to upload these two zip files as is one at a time to the /sys folder using DWC.

i tried v3 but didnt have enough brain power at that time to change all the needed files for it to work.

@Phaedrux
0,0 is in the rear left corner

front right corner is x440,y535

Your config files are already using the format for RRF3, so you'll either need new files for RRF2 or update to RRF3.

See my linked post earlier about why you want 0,0 to be the front left corner. At the very least to understand how to get your prints unmirrored.

tracar

@Phaedrux
i understand that if i modify my physical layout, i can achieve the goal of the correct homing direction .and thus a non mirrored print

But my original question is Can it be changed in the software as so i dont have to change anything physically.

with every cnc i have built. i can easily tell it what dir to home and what axis. this plastic printer just boggles me . lol

Phaedrux

I'm not saying you have to change anything physical. It's all software settings. If you read the post I linked it tells you what had to be set based on your physical printer.

0,0 is just a coordinate. Putting it in the front left matches the slicer and cad software coordinate system.

The endstop position is irrelevant. It can be anywhere you want. The firmware just needs to know where it is based on 0,0 being in the front left.

Your homing moves are set in the homing files. The direction has to move towards the endstop.

The direction the motor actually goes is determined by the direction of rotation which is also defined in software.

tracar

its a bit much for me, i did upgrade to 3.11 but then it took me 3 days to figure out how to downgrade and get the wifi part to connect.. im more a hardware kinda guy. this software is a p-i-t-a for me.

so can you show me a visual example of what i need to change in the code ?

Phaedrux

Sure. Post your current config.g and the results of M115 so I know what firmware you're currently on.

Physical location of endstops is left and rear correct?
