You're a Legend, works like a charm. Thank you so much, it seems simple enough when you see it but I was trying all the wrong way. Much appreciated.

Thanks for your help Veti

It is totally misleading 😉 Because in reality there is also: Friction, acceleration, jerk, driver-behaviour etc. pp. so the paper from faulhaber only gives you a hint of a ballpark where you end up if you use 1/16th microsteps as "possible-stop-positions" (versus the "interpolation/microply to 256" which is basically "smoothness" as dc42 pointed out, so basically quiteness but the stepper can not "stop"/"hold" on those positions. Basically as I understand it, the "interpolation"/"microplyer" is only that you set your voltage and ampere not in one step to the next 1/16 step, but go there via "quasi-sinusoidal" micro-interpolation LookUpTable for Voltage/Ampere so that it doesn´t shake that much)

I would roughly calc with the values in the paper and keep a safe 10-25% distance to it, because of all the other effects not yet in the whole-calculation

I usually use as little "possible-stop-position" hard-microsteps but of course use always the interpolation/microplyer microsteps for smoothnes - less workload for the cpu for the step-calculation, because the interpolation happens in the driver-chip. Also there are theories that it might be beneficial for accuracy if you use only full-&halfsteps as possible-stop-steps. Of course then your kinematics has to be adjusted to that

Hey - please share your thoughts, experiments and conclusions, might be of help for all of us 😉 we wouldn´t be here if there isn´t anything we wanna learn

@fcwilt It now says

When using the Z probe to home Z, M574 Z has no bearing on the probe setup or usage. A Z probe and a Z endstop can both be configured at the same time. G30 calling the probe setup with M558, and G1 H1 Z moves calling the endstop configured with M574 Z.

That seems to clear up things nicely.

Good job and thanks.

thanks i'll give it a go.

Do you have your cura settings properly set up to generate reprap code? It’s looking like marlin output. Check your main settings in cura.

sorry been hecktic busy. Thank you for your advice. I will try see what my Cura is set up to use.

@aidar all good, so its related to the temp setting, T45 as soon as it hits 45 its on anything less and its off. Thanks it works for me

Holy Cow!! How backward can I be. My wires are connected to the endstop. Thanks for the picture, with out it I would have been convinced we where talking about the same thing.
I've just redone it now and started the mess. Looks like its working.
Many Many thanks. You've been a huge help.

My pleasure!

My Apologies, my dyslexia is getting confused between the bootup logo Duet3D and my board(see below)
RepRapFirmware for Duet 2 WiFi/Ethernet version 2.03RC4 running on Duet WiFi 1.02 or later
Board ID: 08DGM-917NK-F23T0-6J1DA-3S86T-KZBWD
Used output buffers: 3 of 24 (17 max)

Does this work with power resume, and if so then what am i doing wrong?

Could be the PWM value for the fan. F parameter

Another user had a similar issue the other day.

How do i tell what thermostat im using?

That can be tricky to find out if it isn't advertised for the printer itself. If it's a genuine E3D hotend, you'd have a semitek thermistor with known settings.

The best bet is to buy a new thermistor with known values.

What is your hotend?

@dc42 Thanks a million, I will do

@petera said in Help With error message:

Hi all, thanks I found a loose sensor. There is no probe. Seems like the home button works now. Im following the instructions using YAT and I am getting the error "WiFi reported error: no known networks found" I see a lot of stuff on the forums so i'll work with those before i cry for help again. Thanks.

Send M587 from YAT to see if your WiFi network SSID is in the list of known networks. SSIDs are case-sensitive.
