Ender 5 Plus CoreXY.

?

Link to this, seem all the Ender 5's are plain cartesian to me.

moe.adams9093

@bearer Your awesome thank you that actually fixes the issue for homing all axis. I thought Ender 5 plus is a Corxy printer. but I'm still having issues with the heater it keeps saying "heating fault on heater 1 temperature rising much slower then 1.7C"

A Former User

For the heater, it would do that if

wired wrong
the fuse is blown
the thermistor isn't working or thermally coupled to heater
heater mosfet has failed in a atypical manor, they usally fail stuck on.

i think, but I was hoping someone else would get that one.

Phaedrux

Have you PID tuned the heaters?

moe.adams9093

Ok thanks, I will look into it.

moe.adams9093

@bearer So I have checked all components with a voltmeter resistance looks good and also I took the hot end block and the thermistor plugged it in back to the original board and it worked fine. The current thermistor connector is plugged into " E0" on Duet 2Meastro. I think its a time issue, because of the error message says that the heating fault on heater 1 temperature rising much slower then 1.7C. I'm new to duet 3d board and I don't know how to tune PID heaters if you have some tips that will be really helpful. but I did view the documentation and I added few codes to my config.g file I post it now.

pardon, I assumed that was done.

look at M303

moe.adams9093

@Phaedrux can you please share how to tune the heater? thanks

moe.adams9093

@bearer thank you

moe.adams9093

when I run the command M303 H1 S240 it will fail tunning error message " tunning canceled because of target temp didn't reach. same thing when I run the command M303 by itself.

PaulHew

make sure your 'part cooling' fan is off

Also you can use this command before the M303
M307 H1 D60
then
M303 H1 S240

Thank you, Paul, still the same issue. very slow to raise temp and it stops at 135c

either the thermistor is reporting the wrong temperature
or your heater is for the wrong voltage and you're effectively getting a fraction of the wattage you expect
or there is alot of losses in your wiring
or leprechauns; idk?

PaulHew

@moe-adams9093 M122 Please.

FYI if you click the button that looks like </>, just above, you can paste your text in there.
ie

https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control

Makes it easier to read!
Also, might worth checking the hotend connections, make sure the ferrules are tight.

Phaedrux

Can you post a photo of the hotend?
Is there something in direct physical contact with the heat block?
Is the fan blowing directly on the block without a silicone sock?
Perhaps the Ender 5 Plus is using a different thermistor than other creality hotends and your thermistor values are completely off.

moe.adams9093

@Phaedrux hello can you please help me solve this issue so my ender 5 plus has 2 Zmotors and when I run G32 it doesn't compensate or level the bed very well it still off from corner to corner so I found that I need to set an independent Zmotors to get auto bed leveling up and running I connected first Z motor LeftSide to Z-drive and the second one right side to E1 I spent days reading the duet form but it's not working for me or I have no clue what I'm doing, if you please point me in the right direction that would be highly appreciated

here's my config.g file

You're going to need to define drive 4 for use as a second Z axis in config.g and change your bed.g to do the probing for the leveling adjustment.

; Drives

M671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis

For the points in M671 you need to find the coordinates of your own bed to measure, you can't just use the example points.

You will connect one Z motor to the Z1 (drive 2), put the jumpers back in the second port. Then connect the other Z motor to the E1 (drive 4)

alt text

For bed.g you'll also have to find the points to probe with G30

G28 ; home
M401 ; deploy Z probe (omit if using bltouch)
G30 P0 X20 Y100 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X180 Y100 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors
M402 ; retract probe (omit if using bltouch)

The G30 P1 will likely be further to the right on your larger bed so adjust the CX position accordingly.

moe.adams9093

Thank you very much for all your help. I will make these adjustments tomorrow, but how can I find points in M671 coordinates of my own bed measuring, is their sort of documentation can explain how to find the coordinate positions of my bed. thank you again

Phaedrux

You just need to choose a point close to the lead screw but still on the bed and both need to be in line on the Y axis.
