@Norder Thank you for your reply, i will look into this.

good day Gurus,

im currently doing a full tear down on my ROBO 3d r1, i installed a Duet 2 wifi board a couple years ago. i picked up a Duet filament run out sensor, and want to start messing around with an accelerometer to test out input shaping.

other than the dozuki doc, I cant find many videos or support on them. i assume its just not a popular upgrade?

either way what I am wondering is do I just securely attach the accelerometer to the print head? I'm assuming it doesn't matter where?

The weirdest thing and I'm not entirely sure when this started however it seems that sometimes the machine has problems deploying the pin, ill go through 10 prints like normal, and everything is working perfect. than it will have trouble deploying the pin. it just sits there and flashes.

i can reset it just fine, some times I can self test it and it works flawless. other times it will make it 2-6 times on self test before it starts flashing and cant deploy the pin.

think I have a bad BL? or is it just a firmware issue?

@bricor ya that did it... not sure why i had such a brain fart... i knew i was following the way some one else did it... i just couldn't find that doc.

ty man I really appreciate it.

here is my config.g

M501

i just turned on my retrofitted ROBO R1, I have the duet2 wifi, with the BL Touch.

everything was working fine until stupidly I decided to update the duet files.

i was 3.1.4.2 and upgraded to current 3.4.2.

home x works fine,
home y works fine
bl doesn't work at all any more, I cannot deploy or retract
I cannot home z

i have been trying to follow this guide https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/#wiring

how ever when i verified the wiring, the guide wanted me to use the heater 7 pin off the main board, except when i set everything up in my config.g it tells me that it heater 7 doesn't exist. so i did what user @dc42 suggested in another post to try to use a different heater. i tried heater 3, only it says that heater 3 doesn't exist either.

Can anyone point me in to the right direction? im completly lost at the moment.

@JoergS5 it was def super weird, i do remember because i had to move the probing to the centre of the bed, i had to be very aware of where the head was, so i shrunk the build volume to confirm, and i guess i never swapped it back.

maybe one day ill mess with it to make it bigger

thank you though!

and to @Phaedrux you guys are the bomb.com

@JoergS5 & @Phaedrux i believe that was the culprit. i have matched the the mesh coords with the bed coords, also changed the build tak plate and shes smooth as a babys bottom now.

so right now, ive used a 0.05 feeler gauge to where it JUST touches the nozzle using 0.01 movements, than i removed the feeler gauge and dropped the nozzle down another 0.05 which should be touching the bed. only it doesnt actually move the nozzle.

its curious. i tried to send an M92 Z0 how it said that the command is sent how ever my z is still reporting to be a 0.44. when i send an M999 it resets like it should but it wont let me actually zero it.

@Phaedrux how ever isnt the probe tip supposed to be at the same level as the nozzle?

all though the BL touch probes at 5.30mm when i actually touch the nozzle to the bed or atleast touch it to a 0.13mm feeler gauge the z height is set at 0.69mm when it should be 0.13ish

@Phaedrux yes a G30 S-1 give me the values of 5.30 consistantly

@Phaedrux also, am printing a bed level test now and its absolute rubbish. worse than before lol...

the front side now isnt printing at all haha

@Phaedrux it does, because as stated previously i would have to redesign the BL touch mount which i will once i can actually print things,

i didnt take into account the pin dropping so unretracted its actually around 2 mm off the bed, which is why when you look at the homeall.g i you can see why i raise the z to 10, before i probe.

@Phaedrux better, but still not compensating on my front corner as you can see.

Here is my new config.g and my homeall.g

@Phaedrux i just re did my spacing for my probe, and you were correct, it was out.

new measurements were x0 y-26

reprobing the bed now and am going to try a test print

@JoergS5 i already did that as @Phaedrux suggested

nah, i manually added metal shims under the flexible metal plate. it looks worse than it is, but i have already adjusted the shims and that hump is now gone.

i have lowered the layer height so that its actually too low and its adhering but its clearly not right yet.

@JoergS5 i did notice that i some times get anomalies just like that, but what i have found atleast on my machine is that it was something mechanical or something weird. but ive always sorted it out.

here is the new mesh level, im going to take out the shims in the front portion to lower it, now that its a little more accurate.

also it made no difference in the first layer print. more towards the front of the bed, it doesn't adhere.

@Phaedrux i also just realized that my values for the x and y arent even close to the min max set in the config, i made some changes just before i posted the homeall.

i also made the changes to the probing, and its probing each spot twice now, and is probing really slowly.

its on its last line now, ill post the height map when its finished
