hbot homes correctly but prints mirrored ,

tracar · 24 Aug 2020, 16:26

so from looking from the front of the printer, my x/y endstops are in the rear left corner,
this is the only place i want them to be due to wiring ease.
now im not the best on programming, but over the past month have been able to get , for the most part, everything to work sorta. thru trial and error, so i may have repeated a few lines here and there....... Z axis works as it should

Board: Duet WiFi 1.02 or later
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)
Duet WiFi Server Version: 1.23
CoreXY

after homing to the left rear corner......., x+ and y+ will move the head towards and to the right of the printer (right front corner)

i also can not figgure out how to get the second z axis to be separate from the first. to use as bed leveling.

i have an expansion board so i can use a closed loop setup,

prints are mirrored, they look good but all are mirrored from the stl.

So basically i like the way it is set up with the homing in the back left corner, but need to get it to print non mirrored, can this be done ?

The printer is a bit messy. but its still in the design steps, once i have the thing printing right , it will be taken apart completely and rebuilt all squared nicely, with a few new parts added.

feel free to make any changes to the code, so i can see how this related to motion.

@tracar

This my guess what happening :-

You have set high end homing ( right ) in your config.g , But your machine uses low end homing .
Your homing files say G1 H2 X300 , which is correct for high end homing , but you have the motor direction wrong too.
So it goes left think it's going right and hit the end stop on the left thinking it's the right end stop.

Two wrong making a right .. and so you have mirror !!!

tracar · 24 Aug 2020, 18:24

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

peter247 · 24 Aug 2020, 18:37

@tracar

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 · 24 Aug 2020, 18:59

@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 · 24 Aug 2020, 19:39

@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 .

what are the 4 control boxes at the back ?

tracar · 24 Aug 2020, 19:54

@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 · 24 Aug 2020, 20:02

@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 · 24 Aug 2020, 20:26

@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.

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

0,0 is in the rear left corner

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 · 25 Aug 2020, 00:28

@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 · 25 Aug 2020, 01:17

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.
