Well it's doubled there...

Yep I Figured that out,l and have zero idea how that happened. I know MHackney was giving me a hand and had me cutting/pasting values from his to my config to get things working, maybe I over wrote that and commented out mine thinking it was a necessary change? I don't know.

Can you help me with my G1 Z0 issue I am having, I Can't remember what I need to change but when I type that it hits the plate and crashes, I'd like for it to be .2 or so mm off the bed but I can't seem to remember what to change. I thought it was the G31 command I used uptop but that didn't work, is it this M208 Z-0.2 S1?

@Phaedrux said in Is there a change in esteps for 3.11?:

I'm inclined to think heater temp issue as well.

When you updated to 3.1.1 did you create a fresh config set from the web configurator or did you manually update your config?

I assume you're using the E3D thermistor from the looks of your values?

Doing a new PID tune would be a good start.

For reference here's what the config tool generates for the heaters

; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138         ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0                                  ; create bed heater output on bedheat and map it to sensor 0

M140 H0                                                ; map heated bed to heater 0
M143 H0 S120                                           ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1                                   ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00                                       ; disable bang-bang mode for heater  and set PWM limit

Starting with that and then PID tuning the bed and hotend and saving the results with M500.

I did not create a new config.g from the tool, I would really like to do that if I knew how to answer all the questions properly. Mine just seems to messy.

I am using the e3d thermistor.

I will tune it now, I figured out my steps value was doubled somehow. I checked my config.g backup I had saved before these changes and it was 415 before but for some reason it was 842. /shrug

So my issue is definitely over extrusion. I did 2 prints, one at .85 extrusion and then at .75 and the .75 is soo much better. Still not perfect but getting much closer.

I also need assistance with my 1st layer. I adjusted what I thought would fix the issue, but I still need to baby step up .5 mm to get a good first layer.

G31 X0 Y0 Z-0.75 P500				   ; More (-) Z is less smooshed, more (+) Z is more smooshed

it was initially Z-0.25 but I changed it to Z-0.75, and I still had to baby-step up.

So now I need to find out the E-Steps for the Extruder motor. I'm so out of practice I don't remember anything.

@deckingman said in Is there a change in esteps for 3.11?:

@sLpFhaWK Have you tuned the heater since converting to RRF3? I don't see any M307 but if you saved the tuning result using M500, then the M307 result will be in config_override.g. - might be an idea if you post that too.

Also, can you confirm that the extruder is using a 0.9 degree motor? The steps per mm are roughly double what one would expect for a 1.8 degree motor so I assume that is the case.

I haven't tuned the heater since upgrading to 3.11 but would that matter if it was tuned on 1.xx?

This is my config-override.

As for the 0.9 deg stepper motor I honestly do not remember. If I had to guess I would say no as I didn't get the stepper through e3d when I had gotten the titan I already had a pancake but if it was configured before on 1.xx and working fine why would anything change in 3.xx?

Should I retune my hotend for the config changes you think?

For example I had gcode I printed on 1.21rc3 and it printed perfectly fine, but since upgrading to 3.11 it printed like hot garbage. I don't know if its over extruding or what, but the prints are terrible.

This is on a D300vs Delta, it has an e3d titan on it and up until a few days ago it printed perfect.

That is with GCode that printed this same exact piece

Same GCode different results.

I was thinking it was a partial clogged nozzle, but I've done cold pulls and the end is coming out clean so I am at a complete loss.

Also where in the config should the m208 go?

Usually after the motor settings, but before fans. But I'd think that the endstop configuration is the main problem.

Re microstepping: actually, M350 X64 Y64 Z64 E16 I1 is probably okay, it just means that you get interpolation on the E axis only. Using x64 on the other axes is fine, though the motors are likely to have a greater margin of error than even x16 microstepping. The advantage of interpolation is that it should make the movement between microsteps smoother and quieter, but changing from x64 to x16 might lose you a very small amount of accuracy.

Ian

Well I am not sure what fixed it, but it seems to be working now.

If you noticed in my config file, before the end switches there was a line commented out.

We had them set to high before, but with the change in 3.0 where you had to define them I guess we just set them low somehow and that possibly was screwing it up.

When I home, and drop it say 200mm and I reset the board I will home it and it will know it's max height and won't add the 200mm giving me an error anymore. I'm going to revert back to X1 Y1 Z1 to test and see if that fixed the error.

So I can confirm, the X2 Y2 Z2 fixed the homing error.

Thank you for the help @droftarts and @dc42

@sLpFhaWK said in Homing issues on 2 delta printers after upgrading to 3.1.1:

M350 X64 Y64 Z64 E16 I1

Also, as you're using Duet 2 Wifi, you won't get interpolation (I1) with microstepping set to x64. The TMC2660 stepper drivers only provide interpolation at x16.

Ian

Ian, so should I change the

M350 X64 Y64 Z64 E16 I1

to

M350 X16 Y16 Z16 E16 I1

or just remove

M350 X64 Y64 Z64 E16

I'm sorry I got help from Michael when he configured this printer for Brad, so I, and pretty much everyone else who bought one from Ultibots is running the same values.

@droftarts said in Homing issues on 2 delta printers after upgrading to 3.1.1:

@sLpFhaWK
Is this how your endstops are still set?

M574 X1 S1 P"xstop"   ; X min active high endstop switch
M574 Y1 S1 P"ystop"   ; Y min active high endstop switch
M574 Z1 S1 P"zstop"   ; Z min active high endstop switch

If so, they are set as LOW END endstops, ie when axis is at minimum, with X1, Y1 and Z1! They should be X2, Y2 and Z2.

You don't appear to have an M584 command in your config.g (which sets the drive mapping). Add:

M584 X0 Y1 Z2 E3                           ; Set drive mapping

after the M665 and M666 lines, but before the M350 line, in your config.g. I don't think this is causing your issue, but it should be defined with RRF3.

Also, might be worth setting axis limits with M208, something like:

; Axis Limits
M208 Z-0.2 S1                               ; Set minimum Z

Ian

Ian, I haven't touched anything in the config, so if that is where you pulled the code from they are indeed unchanged.

I'll add the M584 and change the XYZ from 1 to 2.

Also where in the config should the m208 go?

@dc42

This is where I started.

Then I'll run the 2 commands you set.

G91
G1 H1 X1000 Y1000 Z1000 F2500

This is what I got with the M114

@dc42

I can confirm that yes, all 3 switches are being triggered when they were all at different heights.
