No moving printerhead after homing my delta

@zapp3r said in No moving printerhead after homing my delta:

thanks, this is a bug I have changed it to your code.

If it was homing with the original configuration - switches set at low end - with the switches actually at the top??

You presumably need to reverse all the motor directions as well??

[Zapp3r]

@rjenkinsgb : to check the direction: the endstops are on the top.

after homing:
G91
G1 H2 X-10
X-Tower moves 10 down

is this correct?

Homing is in the correct direction -> it´s going up to trigger the endstop

Interesting: it works in both configurations of the endstops.

Yep, just tried it on my delta (Kossell) and that moves one side down by 10mm.

What is the displayed Z position after homing?

Edit - try
G90
G1 Z100

@rjenkinsgb: no movement after G1 Z100 - should go down to 100mm above bed. there ist no aktivity - even no sound of the steppers (e.g. to high frequency, or something like that).

G1 Z100 F300 for a slow motion does nothing too.

only movements in relative mode while adressing the towers

@alankilian: thanks for your config. I checked it and i´ve seen no significant changes - ok, i use two tools with offsets - nothing is 4 me quite relevant in the overview.
tomorrow i will copy your configuration on my printer to see if it is moving - maybe an error around the 2nd tool or with the DuePanel.

i will report

After homing the towers what happens if you send a simple G30?

[Zapp3r]

@phaedrux: same thing - nothing happens and i get the error: "Probe was not triggered during probing move"

[Zapp3r]

@alankilian: your config works fine! movements are possible as it should be.
in my next break i will replace part by part to identify the error - coming soon with the solution
(...or with the core of my problem )

@alankilian @rjenkinsgb @Phaedrux :
the solution is ultra stupid

it is my mismatch between radius and diameter...

Orignal line:

M665 R717.765 L682 B500 H600                           ; Set delta radius, diagonal rod length, printable radius and homed heigh

the length of the rod does not fit to the printer radius!

the correct config line is:

M665 R358.883  L682 B250 H600                           ; Set delta radius, diagonal rod length, printable radius and homed heigh

Here is an error message quite helpful - from check perspective quiet easy to calculate.
Maybe this is possible to include while interpreting the config.g.

Many thanks to all for helping in this forum

@zapp3r Good news. I'm glad you got it figured out.
