Great video thanks ! In the Marlin 2.0 configuration, how and where should we define for example that the "driver #5" is associated with "Z2" as far as it is necessary ?
If you're only using a single extruder then e1 becomes z2. And you do this in the stepper section like in the video and uncomment the z2 driver. And make sure you specify like the video in configuration.advanced that you have to z steppers.
Do you happen to have a video explaining Auto Build Marlin?? This made dual Z fairly easy to understand, now for the hard part, at least for me. I suffered a brain injury a few years ago, and all the other videos I have watched on the subject are too difficult for me to keep up with, my concentration abilities aren't what they used to be.
But you make aligment to the bed. It can go wrong if the bed not straigth to the XY. Check your perpendicularity on XZ. Check Prusa process. It make same position on the top before homing if you make aligment. Anycubic Mega S use two endstops on each Z motor for making a good perpendicularity on XZ. Level the be to XZ not inversely.
If you are not going to use e1 as the second Z stepper it will never work. The steppers must be driven independently. If you use the two plugs by the z stepper driver it doesn't drive the moters independently. Hope that helps
Hi Great video. I was wondering could you explain if the auto alignment could be achieved with 2 end switches left and right and how. I have a MKS Tinybee v1 populated with E0 E1 TMC2225/2208 stepper drivers but only has X/Y/Z end switch position on MB. I'm assuming you have to define a pin normally used for a probe as the other end switch. or maybe some other pin. or can I just connect the extra end switch to the probe switch or do I have to tell Marlin to redefine the pin. as well. Oh I'm upgrading an Anycubic Mega pro because the screen and MB is faulty. I don't need the laser feature. Thanks
Wow, just about stepped in it! Apparently the SKR Mini E3 V3 has 5 motor _connectors_ but only 4 motor _channels!_ If anybody knows a good Ender 3 mobo replacement with 5 stepper drivers, I’d like to know.
I pretend do doble z belt on my printer...the question is: can i use the command just for correct manually the mechanism? I will use only one stepper motor.
On a tronxy X5SA with BL touch and SKR 1.4 (Independend stepper motors and drivers) it works but keeps the acuracy to 1.70. How can I tell what stepper is the left and the right? Also, when probing on the right it moves almost to the middle of the print bed. Can you make a video and show us how to set the offsets to actually probe the edged of the bed?
Depends on the board creality normally does not put the other stepper chip on the board so you need to change the board to something with an additional stepper driver.
good morning. I have a problem with this function. I followed your video and once the iterations are finished, the nozzle comes crashing down on the plate to the left of the plate
Great video. Thank you. I've already moved the motor to its own driver, just need to make the rest of the firmware changes. My problem is related: I've decided to keep my Z-endstop in addition to my probe. So it homes with the end stop, and makes a bed mesh with the probe. The only problem is that I no longer can adjust my Z probe offset in either positive or negative values. Any advice? Thanks again for the great guide! :D
Not working for me x.x it just brings the printer out of whack. When i swap Z1 and Z2 motor connectors on mainboard, it brings the printer out of whack even faster.
@@GregTheroneggythetech Geeetech wood-frame i3. GT2560A+ electronics. Different drivers, but Z1 and Z2 (in E2 socket) are A4988 temporarily. Marlin 2,1,2,2. For probing i have a 9g servo attached to the part cooling fan, which swings down a mouse button switch connected to Z-Min port. I was using M6 threaded rods for Z movement but now replaced them with precision T8x8 leadscrews. I think they may have revealed some misalignment from Geeetech's CAD errors in the frame design :D But i'm not actually hearing motor snapback?

The motors get pretty toasty, but the drivers are cool, they've got a ton of airflow.
Ah it's working now and it the scale value doesn't seem to matter too much. I have set it to converge only to 0.1mm because i don't need the motors to be exactly tram, because nothing else on my printer is :D I basically beat and bent the mechanics into shape a little and then i had a bad feeling about one of the A4988 drivers because it would make the motor emit horrible noises whenever i would probe its VRef so i took both out and put in others that i know are good... they turned out substantially better too. I mean you don't expect an A4988 to sound nice exactly, but some are less horrible than others because of differences in decay tuning. I'm getting in another Trinamic in a few days and moving to a different mainboard as well, i basically found a bunch of unused pins and managed to solder to 5 pins 0.5mm pitch right next to each other and made it to a connector, secured everything with Kafuter silicone, now just need to wire them up to the StepStick sockets. I had already modified Marlin to be able to access these pins, pins which do not exist on an Arduino Mega so they weren't supported. I had already been using this trick on this mainboard for E motor to set it to SpreadCycle mode (turn off StealthChop) but i broke the connection recently. So when the new driver arrives and when i'm moved to GenL board, i will have a full compliment of Trinamic drivers on all motors which i can then also tune properly and tune out their quirks. It's an old V1 GenL that i got as a firmware development mule so i don't foul my printer, but the boards were always intended to swap places eventually. The GT2560A+ had a little combustion event as well, i had to rebuild a small chunk of it; bad solder joint from factory because they forgot thermal reliefs, but like the defect was SO well hidden i mean i have an eye for this sort of thing and there's no way i was able to spot it. Luckily Marlin's Thermal Runaway alerted me to the problem before it became a bigger combustion event. Trinamic can misbehave though this is why i fall back to a4988 for testing as well occasionally. Trinamic are actually internally microcontroller based and sometimes particularly on the 2208 and the 2225 that i have the micro can just lock up due to ROM firmware bugs :3 i think the 2209 and related ones are less buggy, all the newer ones.
Are you using Factory board on cr-10 V2? My board has 5 stepper drivers but it's using single stepper for Split Z however there is additional stepper driver 2208 which is not being used, can I reassign the drivers in anyway so each Z uses its own driver on factory 2.21 board?
I also have the same Creality V2.2.1 board in my Sovol SV01 and I followed this video exactly, bu moved my second stepper motor connector from Z2 to E1 on my board and it worked great then.

How many stepper drivers do you currently have in your turbo? If you have five you can do this. Quick mod of the configuration.h and the configuration.adv. and you're good to go. Did you set up your Skr turbo?
How often should this calibration be done, before every print? Do you need to save the final calibration in the eeprom? Sorry for all the questions just trying to wrap my head around this process.
The v king 400 looks really nice. I really like my cr-10 v2 it gets very consistent prints. But I did not pay full price for it. I got it on Facebook marketplace for a screaming deal. I would definitely think it's worth the price I'm getting very consistent prints. My Chiron is 410x420 but I don't seem to use that volume enough. And the price was pretty good on that as well.
