Thanks @chrishamm !

The only way to figure if it could be loaded, was to load the height map before homing so to get the warning message!

Have a good day!

@3DPrintingWorld said in Height Map recall:

ay to verify what height map is being used if one is called before a print?

I am coming with the same question. On duet wifi 2, I upgraded to 3.01-RC9 and Duet Web Control 2.1.4 but loading the height map either with G29 S1 or through the Dashboard tab -> Compensastion & Calibration -> Load saved height map from SD Card the "Disable Mesh compensation" remains disabled.

I see in the diagnostics the following even after I Execute G29 S1 or G29 S2

=== Move ===
Hiccups: 0(0), FreeDm: 169, MinFreeDm: 169, MaxWait: 0ms
Bed compensation in use: mesh, comp offset 0.000

Is this an issue with my configuration, some bug or anything else? I can see the height map from the height map tab but cannot tell whenever it is active or not even if i turn debugging on/off.

Have a good one!

They did catch up quite fast to be honest

@peter247 said in Silicone Heated Bed:

I was hoping to find a UK reseller , but it looks like I may have to go by the slow boat from china route.
Due to never ordering from outside the EU before I`ve looked into the customs / duties / tax etc I would have to pay extra for anything from china.
Which being under £135 I think would cost me just VAT on top ?

Cannot tell for UK though as I live in Greece and I usually buy from banggood. Nothing has gone through customs so no any additional charges. Anything more expensive will go through Netherlands and it will seem like being sent within Europe. There are usually three shipping methods available. The cheapest one and slowest, the airmail priority and a third more expensive and fastest one. Picking any of the first two won't go through customs. Additionally, anything that goes through customs apart from the VAT you will have to pay an additional customs' fee.

I wonder if there is anyone here who can confirm for UK.

I have a 30cmx30cm heated bed at 750W and it takes approx 2:54 minutes to reach 70c

So you had the titan aero assembled, which was working fine until you upgraded the firmware. This is strange indeed.
How fast do you extract? Usually for steps calibration I go as low as 160mm/min (2.6mm/s).

Did you extruder came with bushings or bearings? While extruding do you notice any jam at all, like the extrusion slows down or something?

Since you changed the current to 1.4 and overextruded the only thing that can think of, is that there must be a high friction issue with the extruder. How did you tighten the heatsink? I had a friction issue which i managed to solve by tightening the screws from top right (the freewheel and bearings location but very gently) , right bottom, top left and left bottom. E3D last time i checked suggest the right process should be from top left, bottom left, and move on the right side which didn't work out well for me. Tried it with both bearings and bushings and there was always some tension and minor misalignment when i was following their suggested sequence.

Something else you need to consider is in case if you are using the pancake motor (slim nema motor) is that you are close to its max amp rating and you should be somewhere around 80% of this number (1.4).

Someone correct me if I am wrong but shouldn't the line below

G30 P12 X0 Y28.65 Z-99999 S6

be something like below for the 13 points?
G30 P12 X0 Y28.65 Z-99999 S13

No firmware update has affected my titan aero.

I would like to ask you how old is your extruder? I'm asking you this as there was an issue with the titan aero bearings. I had my aero working great until I moved it onto my new coreXY and and the extrusions were inconsistent. It took me a while before i eventually figured out that the bearings were causing this problem due to a friction increase as a result of not only missing steps but also the extruder was getting jammed.

With new bearings I can still use the pancake (slim nema motor that comes with aero) but I still had to increase the current to 1000 (M906 E1000 I50)

I am currently using x16 microstepping and works great

M350 E16 I1 ; Configure microstepping with interpolation
M92 E950 ; Set steps per mm

I had to lower my probing speeds and also introduced a recovery time. Still the probing heights changes range between -0.03 to 0.03 but my prints especially the first layer never caused me any issues.

@dc42:

In your homeall script, this line:

G1 S1 X5 Y5 F1000 ; go ahead a few mm

probably won't work because X and Y are already homed at that point. But as they are homed, you can omit the S parameter completely from that line.

In your homez script, the only line where it's essential to have the S2 parameter is the first G1 line. After that the Z axis is homed, so G1 commands without the S parameter will work too.

Well spotted! Thanks

I have a CoreXY so sending any movements using S2 for X and Y won't result to a movement on a single axis.
Instead, even without having any axis homed, I still use S1 ie. G1 S1 X10
I only use S2 for the Z as described in the notes.

I don't know if this is the correct way but I won't exceed any limits

My home all script is as shown below:

G91                     ; relative positioning
G1 S2 Z5 F1000          ; lift Z relative to current position

; << Home XY >>
G1 S1 X-305 Y-305 F6000 ; move quickly to X or Y endstop and stop there (first pass)
G1 S1 X-305             ; home X axis
G1 S1 Y-305             ; home Y axis
G1 S1 X5 Y5 F1000       ; go ahead a few mm
G1 S1 X-10 F800         ; go back to X endstop slower this time
G1 S1 Y-10 F800         ; go back to Y endstop slower this time
G90 

; << Home Z >>

and this is my Z homing:

@bartolomeus:

I got a deviation of 0.007 with my bltouch using a repeatability test macro found here somewhere. I remember getting the same result using marlin.

Using marlin and ramps i had pretty much similar deviation. Now on my new coreXY i get a deviation of around 0.02 - 0.06 unless i go very slow at around 120mm/min
I am very interested in your scripts (config, deployprobe and retrctprobe).

Came here to report.

CoreXY with bltouch and multitouch probing enabled with Probe 5 (P5), prints and everything works fine. Also the web interface feels more responsive.

Are you running this supply just for the bed? For a bed this big (300x300) I went for an AC powered bed. It reaches 70C in about 2m.

Thanks, you are right here about the 1/16th. I tried to replicate my settings from ramps. I will probably try this out without the hot end and see how it will work.

Hi,

I believe I have tried my best to resolve this problem without any success.

I have installed Duetwifi (1.21RC1 firmware) on a new CoreXY Build with a new Titan Aero extruder along with a nema 17 1.8 motor. I cannot tune the Extrusion steps as they are always inconsistent especially after I switch duet off and back on again. But the error is weirdly consistent. As an example, I have a 120mm mark on the filament. Extrude 100mm and find the distances of the mark. even if i get it right and see the 20mm mark on the filament and power duet off and back on again the mark is an additional +5mm for the next 3-4 extrusions.

The filament I use is PETG and I extrude at 230C. I tried to extrude both from the interface 100mm at 5mm/s and manually executing G1 E100 F180. At this point i have run out of options. Is there anything else I should check?

Edit: Grammar check

Edit: Something that I forgot to mention is that the new extruder came with bushings instead of bearings which definitely causes some extra friction. Nevertheless, the motor seems to work smoothly. I wonder if there are any settings that I keep missing though.

Thanks, I'll do

Hello everyone,

Today, I installed (almost) my new DuetWifi, and accessing the Duet Web control for first time whilst being powered on a 24v power supply (350w) and got spammed with this warning:

I've double checked and triple checked everything and all my wires are correct. As a matter of fact even without having anything connected to the drivers, (only power wire and heated bed) I still get this error.

What's are the benefits of enabling micrtostepping with interpolation other than keeping the noise down?
