Many errors during configuration with RRF tool

Phaedrux

Well you want it to stop before the nozzle hits the bed. You want Z0 to be when the nozzle is touching the bed. If you have a gap, you can edit the homez.g or homeall.g to mark the Z axis at a position that takes that gap into account. So if it stops when it's 1mm above the bed surface, you can add G92 Z1 to just after your z homing move to tell the firmware that the nozzle is 1mm above the bed.

droftarts

@genioluiz7 the endstop can’t be physically above the bed surface, or it will stop the nozzle reaching bed surface. Can your bed be adjusted? If so, I’d move the endstops to a point where the bed is halfway on its adjustment. You also need to get the endstops level, so the gantry is level, then level the bed to the nozzle.

Realistically, this isn’t a good way of homing Z; there’s too many things that could go wrong and cause a nozzle crash.. A Z probe would be a much better idea. Or set the endstops at the maximum end of the Z axis, home to there, and adjust M208 for the maximum travel. This also means recovery after a power failure mid print is easier, as you can home Z without hitting the print.

@droftarts Ok many thanks for your help. Now I've tried to launch a Chiron level test. Seem that the plate dimension or position is not understand from the start of the process. See the following picture maybe is better to show you the problem.

Phaedrux

When you move the nozzle to the 0,0 XY position where does the nozzle actually end up on the bed? You likely need to adjust your M208 values such that the 0,0 point is on the front left corner of the printable area. If the endstops move the nozzle off the printable area of the bed, you can use a negative value for the M208 minima. (assuming the XY endstops are on the low end)

@Phaedrux many thanks for your help. I solved almost every issue. One of the remaining is the following.

When the right z motor get the position between 3.50 mm and 6 mm seems like is loosing power, and next the axis rotate backwards, while the left z motor remain stopped.
What do you think, is the problem hardware or software?

First position
second position

z motor

Remind me how you have your z motors connected to the duet and how they are configured in config.g.

It may be that your motor current is set too low. Do you know the rated max current for those motors?

The right z motor is connected to Driver 2/ZA with the jumpers
The left to Driver 4/E1 motor.

I post all the config.g but I think that what you ask for is only this one:

Maybe E800 is the current for Driver 3/EO motor (the extruder)
and we need to add
the current for Driver 4/E1

M906 X800 Y800 Z800 E800; set motor currents (mA)

@genioluiz7 said in Many errors during configuration with RRF tool:

No that's correct for setting motor current. It's per axis, not motor.

Are both Z motors identical?
Do you know the rated max current for the motors?
Do they have a model number?

In the config that Herve shared above, he is using M906 Z1000 instead of 800, perhaps your current is set a bit low.

Are your lead screws lubricated?

genioluiz7

M906 X800 Y800 Z1000 E800 I50 ; set motor currents (mA) and motor idle factor in per cent

Are both Z motors identical?
Yes, they are. I measured them, both are 4x4x4 cm
Do you know the rated max current for the motors?
Unfortunately not. How can I reach that information?
Do they have a model number?
Not, I tried to find that number also on the x, y and E motor because seems that they are the same but nothing. The only thing that I noted is on the E motor, what you se in the following picture. Maybe it can help.

I'm refearing to that XY on the bottom of the motor.
Are your lead screws lubricated?
Yes

Maybe you're right. This is the Herve M906
M906 X800 Y800 Z1000 E800 I50 ; set motor currents (mA) and motor idle factor in per cent

Instead in my M906
M906 X800 Y800 Z800 E800 ; set motor currents (mA)

Do I need the Idle factor?

I'll post also the old config file of Duet. This is the one before I updated the firmaware.

About this config:

It was set by the previus owner of the chiron
I don't know if it is correct
the firmware version is 1.21

They were using higher motor currents, so it would be worth trying the higher values.

genioluiz7

@Phaedrux
Do I need to insert the idle factor?

@genioluiz7 said in Many errors during configuration with RRF tool:

If you want to reduce the motor current when idle, yes.

genioluiz7

I think I've set every error in the configuration. Therefore I want to say thanks for your help. Very appreciated.

Now remain only another problem to set on my Chiron but I think it is no more about the configuration tool. So I will discuss it in another chat. See you soon.
