@phaedrux I done this today but you need to add extra post processing to simplify 3d very important is to not to put 4.5mm (like in that tutorial ) but 4.5000

{REPLACE "G1 E-4.5000 F4800\n" "G10\n"}
{REPLACE "G1 E-0.0500 F4800\n" "G11\n"}
{REPLACE "G1 E-0.0500 F1440\n" "G11\n"}
{REPLACE "; inner perimeter" "; inner perimeter\nM204 S1500\nM205 X20 Y20"}
{REPLACE "; outer perimeter" "; outer perimeter\nM204 S500\nM205 X7 Y7"}
{REPLACE "; solid layer" "; solid layer\nM204 S700\nM205 X10 Y10"}
{REPLACE "; infill" "; infill\nM204 S1500\nM205 X15 Y15"}
{REPLACE "; support" "; support\nM204 S1500\nM205 X20 Y20"}

{STRIP "; postProcessing"}

and i also added some settings to start script for M207

M207 S4.5 F4800 Z0 ; set retraction length / speed

I'm just not sure why here is also M208 in this tutorial

M208 S0 F480 ; set retraction recover speed / adjustments

because for unretract speed is M207 Txxx

and then run some test prints with 4 small objects

and after using this scripts i ended up with
M207 S4.50 R-0.10 F6000 T4800 Z0.1 for Ziro White PLA

@fcwilt

OMG I posted wrong file at the beggining my fault sorry Z has 1600 steps on the machine

it's my fault when I was posting i used winmerge and probably copied from wrong window

but like i wrote in my last message Z axis is not stoping after first contact of bltouch with the table and pin drops meantime Z is traveling forward nozzle and bltouch I will try to make a video today and upload it somewhere to show you

@fcwilt

its not a regular 8mm printer

STEPS are correct for this axis end of discussion about steps for Z axis please

there wasnt any hardware change just firmware upgrade ( post 1)

again the problems are:

1: super slow movements homing and normal movements on all axies x y Z
2: Z axis continues movement forward bltouch after first touch and it should stop and reverse a bit
3: almost instant deploy of probe pin after first touch of bltouch to the bed surface

so this is nothing with mechanical issue ...

@droftarts said in Bl touch problem and slow homing speed after upgrade to 3.5.4:

Hi Ian

steps for Z axis are correct as this is very dense thread and it is ok

about that

M558 K0 P9 C"^zprobe.in" H5 F120 T6000

when I firstly set this option like that Z ( table in my hevo was going down so i reversed that with ! so then table is moving to BL touch probe.

F500 was set for tests and there is no difference between 120 and 500 thats the problem besides I can see how super slow are other moves like homing or normal travel of the axies .

BL touch is perfectly fine it was working befoure FW upgrade so no hardware malfunction here .

day befoure FW upgrade I was using printer and as you can see in my 2.0.2 config same steps now a bit more Amperage on the motors thats it .

401 and 402 are working fine

deploy probe :

M280 P0 S10 I1

rectract probe:

M280 P0 S90 I1

all checked and it gives same behavior like 401 and 402 also all scripts for bltouch works fine so i can reset alarm etc etc .

and yes bl touch making self test at the printer start.

here is test of new homez.g

;;M98 Pretractprobe.g     ; retract BLTouch
M402                    ; retract BLTouch

as there is no need to try home all if homez because of that strange bl touch behavior is not solved.

I will be away for a week or so so .

Hi all

After years of using 2.0.2 firmware I decided to upgrade my HEVO to newest 3.5.4 firmware and I fallowed documentation so fist update to 3.0 then to 3.2.2 and then to 3.5.4 the only change I done was a change of pin for bl-touch pwm signal from heater 7 ( on 2.0.2) to heater 3 (pin 8 on duet wifi 1.02) but this was made after i observed problems with bltouch just to check.
Now i think I converted my config correctly for 3.5.4 fw but I observed that travels speed is super low ( when moving axies via DWC ) and the most important when BLtouch touches first time bed when trying to home Z it release pin after it goes up and meantime bed is still moving up and not stoping after first touch and not reverse movement ( down ) after that touch . it looks like it is not making any pause on bl touch behavior after first touch and also Z axis continuing moving in the direction of the homing

I really need some help from you guys as I didin't use that printer for some time and now it's needed to print soem bigger parts and I just can not do it

I was even thinking of erase duet somehow and just put 3.5.4 is there way of doing that as well , maybe something went wrong during updates ?

should I move bl-touch to heater 7 pin in duet like i had it befoure ?

@phaedrux

probably there could be also other option to change retraction generated by simplify 3d

in g-code tab tick m101 m102 m103 option
and in post process put this

{REPLACE "M101" "G11"}
{REPLACE "M103" "G10"}
{STRIP "M102"}

I will check this tomorrow at work

with that option will be easier to just copy and paste script to another profile

@phaedrux I done this today but you need to add extra post processing to simplify 3d very important is to not to put 4.5mm (like in that tutorial ) but 4.5000

{REPLACE "G1 E-4.5000 F4800\n" "G10\n"}
{REPLACE "G1 E-0.0500 F4800\n" "G11\n"}
{REPLACE "G1 E-0.0500 F1440\n" "G11\n"}
{REPLACE "; inner perimeter" "; inner perimeter\nM204 S1500\nM205 X20 Y20"}
{REPLACE "; outer perimeter" "; outer perimeter\nM204 S500\nM205 X7 Y7"}
{REPLACE "; solid layer" "; solid layer\nM204 S700\nM205 X10 Y10"}
{REPLACE "; infill" "; infill\nM204 S1500\nM205 X15 Y15"}
{REPLACE "; support" "; support\nM204 S1500\nM205 X20 Y20"}

{STRIP "; postProcessing"}

and i also added some settings to start script for M207

M207 S4.5 F4800 Z0 ; set retraction length / speed

I'm just not sure why here is also M208 in this tutorial

M208 S0 F480 ; set retraction recover speed / adjustments

because for unretract speed is M207 Txxx

and then run some test prints with 4 small objects

and after using this scripts i ended up with
M207 S4.50 R-0.10 F6000 T4800 Z0.1 for Ziro White PLA

Hi guy sorry for maybe lame question but i just get duet and made firmware upgrades and starting to test all on my printer and now i can not find any info how can i set a proper type of nozzle termistor
