Having trouble calibrating towers

[dsl158]

Ive been using this video to calibrate it but whenever I get to script 4 it just crashes into the bed. Ive lowered the horizontal radius so much. At one point I lowered it to 2 and it still crashed. HALP

I've seen that video and it's great but follow the manual. Gene gives a lot of tips and possible mistakes.
Maybe you missed something when doing the calibration.

Also, check if you have EEPROM activated. It's unlikely but it won't hurt looking.

#define EEPROM_MODE 1

Should be =1. If =0 then it's disabled.

Ok im going to check the manual. anything specific that he missed?

I forgot how funny the manual is

It doesnt seem like I missed anything. also my printer doesnt really seem like it is reacting to the change in the horizontal radius

Are you homing after each adjustment?

yes

[Tincho85]

Are you running the scripts sequence after changing the horizontal radius?

When you change the horizontal radius, the center of the bed will remain the same. What changes is the height of the 3 towers.

my problem is when i run script 4
G28
G0 z0 f3500
it just crashes into the bed

[Tincho85]

I know, what I'm trying to say is that when you change the horizontal radius if you run script 4 again it will be the same. It won't change that height.
You need to re-adjust the height of the 3 towers.

I did and still no dice

[Tincho85]

Then I'm lost
Let's wait for someone with other ideas.

Hope you can fix it.

ok

So if command sequence you are using is go home then go to Z0, and it results in a crash, there is good evidence that Z height needs to be changed.


I try to keep these rules in mind:

Changing the horizontal radius does not change height at center.

Adjusting the horizontal radius changes the "flatness" of XY movement plane.

Adjusting the endstops tilts the XY plane in relation to the bed plane. It also has impact on Z height.

but before I start using scripts I set the z height

Did you set Z height in eeprom, or did you set Z zero via the LCD panel?

I have had issues when using the LCD to set Z zero. It worked fine when adjusting center gap, but then the confirming step resulted in a crash. Maybe something wrong in firmware. I use the LCD to adjust the gap, then take the new total Z height and edit the eeprom values.

Be aware that the looping sequence of adjusting an endstop, homing, running a tower macro is fine for setting the "levelness" of the bed, but until horizontal radius is correct, home-then-center-macro may result in a crash.

I set it with the lcd

But the eeprom changes when I set it on the lcd so I dont think thats whats happening. Also ive printed with it before its just now I actually want to print things that are larger than the middle.
