I'm using a UBL - had to add the code manually....

G29 A ; Activate the UBL System.
G29 L1 ; Load UBL
G29 J ; Quick 3-point level

Would be nice to have it in the tool

In the Start GCODE, the M109 is configured as "R[HotendTemp]"

My Ender 3 Is configured to run on Klipper, it seems that M109 R[HotendTemp] is not supported.

Perhaps changing it to M109 S[HotendTemp] solves this, im testing that now.

In the "Settings" worksheet some values are input from the user, other ones are calculated.
It's good practice to fill with a pastel color the cells the user should touch, leaving no background for the calculated values.

Hi. I'm using klipper and was really looking forward to using this tool. However, the code doesn't even start. After heating up, it gets into position and I get the message:
Move exceeds maximum extrusion (1.924mm^2 vs 0.640mm^2)

I'm not sure how to fix this. Can anybody help ?

For dual extruder RepRap style clones the extruded blobs are too tall and get hit by the extruder when the extruder moved from one location to another.

In slicers when printing items one at a time there is a setting which has to be taken into account to avoid hitting the gantry for the extruder. for example "gantry height" in cura. For my printer BIBO 2 this is about 12mm in z. The area of the dual extruder print head could also be considered as should the X and Y rails. but generally just the 12mm gantry height is considered to avoid hitting parts and knocking them off the build plate.

Sadly due to this issue I can't run this profiling tool. please consider adding a "gantry height" interference check.

The blob from one extrusion stayed stuck to the nozzle and crammed itself into the bed during the next blob's purge line, breaking the silicone sock on my Revo. :( There needs to be a lift & pause introduced at the end of the blob to allow the operator to ensure the nozzle is clean before the next purge line.

I am running Klipper. It seams it prefers G1 over G0. Additionally the starting height for the "Blob" could start higher. I don't think sticking to the bed is necessary. I do understand and agree with the wipe after the purge, so if it doesn't change I undertand.

DOE setting with Temperature Spacing and flow spacing can generate gcode larger than bed.

code does not have a check to prevent generate gcode which prints off the bed.

At the moment, the GCode only waits for the bed to come up to temp. This is incorrect in the case that bed comes up to temp before the extruder.

The GCode should wait for the extruder to come up to temperature too using the M109 gcode.

On the analysis tab, assuming 0% based only on the 2mm/s rate for a particular temperature underestimates the underextrusion at low temps. In a multi temp series, setting the baseline to the highest observed weight (probably the slow hot blob) may give better absolute numbers. This is trivial to add in Excel, but many users probably don't check the underlying formulas.

An option to fill in measured weight from a 200mm length of filament could also be an interesting addition even if there are better calibration tests for dialing in the last few percent of flow multiplier for real world performance.

Extruder heating is turned off prematurely while still printing the very last Printblob.

Hi,

im using the script and I have also tried the app.

The prints starts normally but in the middle of extruding the first blobb the printer stops. No error, just no movement at all.
Im using a normal marlin based printer. Any ideas what could cause this?

Cheers.
F-

Setting the bed dimensions should allow for the auto-spacing of the pattern to fill the bed and avoid nozzle collisions with already extruded blobs.

Direction Front to back or back to front doesn't work as expected for origin centered beds and only prints in 1/4 of the bed space,

Tool should consider Bed origin like slicers do and then offset print locations based on the bed origin location. My RepRap style Clone dual extruder printer has the origin XY (0,0) at the center of the bed resulting in only 1/4th of the bed being used (positive print locations).

Printer BIBO 2

i have a cooling fan duct in from of the printer thats very close to the heat bed.
so if you make the first test is will squeeze the first test result during the 2nd test is made.
this could be avoid with a start at the rear and first do all test in X direction

Hi, thanks for your hard work on making this can't wait to try it!

I thought I would ask for a feature whilst I remember

Would it be possible to have two separate start flow rates. My thinking is I can do one at 5mm3 as a base but then start the rest of the test closer to what i know the hotend is capable of so start at 20mm3 in 1mm3 increments to 30mm3. Or should i just start at 20mm3? (Dragon HF + CHT)

I suppose I could run the tests twice to narrow down the target

Off topic, was there an easy way to export the gcode? I just copy pasted it into notepadd++ and saved it as .gcode

The other thing I thought about was print_start and print_end for the klipper users but this might be confusing for everyone else

I generated some G-Code with the spreadsheet, and on the first blob noticed my extruder clicking. This turns out to be because the temperature had been reset to zero. I looked into it, and it seems that on Klipper, a command like M109 Rxxx will set teh extruder temperature to zero regardless of the value of xxx. The Klipper docs say that M109 Sxxx will always wait for the temp to stabilize at the requested value.

So perhaps add an option to generate M109 S instead of M109 R for those of us using Klipper.

Displayed Text with M117 command is only in sync during the "purgeline". When the corresponding "Printblob" is printed the text from the following M117 is already shown on the display.

I was hoping there's a way to add support for circular beds for Kossel/Delta style printers. I have an Anycubic Kossel Linear Plus upgraded with a SKR 1.4 Turbo, a Mosquito clone and a BMG extruder in a bowden setup and I would love to know how much faster I can push it.
