Hello everybody,

Below I would like to introduce you my project here, but briefly something about me:
My name is Thomas, I am 53 years old and I come from near Augsburg-Germany.
For about 30 years I have been to do with plastics processing, especially injection molding and project management of injection molding tools. The last years I have to do with the conveying, dosing and drying of plastics, ranging from micro devices with 100gr/h up to complete hall equipment with several 1000kg/h material turnover.

My contacts with NC-controlled machines started in my apprenticeship. As an industrial mechanic I learned to operate turning and milling machines.
After the apprenticeship I made sheet metal parts in a special production. The unwinding of the developments of the designed sheet metal parts were created "by hand" and initially written without post-processors in G-code for sheet metal working centers (Trumpf mills). These programs were converted on a perforated tape printer into a few meters of punched tape, carried to the machine and read.

I have never built a printer, and have spent the last few months to get learning half-knowledge. First of all the different design principles (Delta, CoreXY, etc ...) recognized, then annoyed with the many abbreviations and technical terms and started to determine my way the construction or imitation of a CoreXY.
To make matters worse, that the acquisition of information was hampered by my bad English. I often do not understand what the meaning of the Translation is - but "Miss Sophie, well, I'll do my very best!"

Now to my project: I call him POLLEYX-CUBE!

It will be a CoreXY of 3030 aluminum, 2 x ball screws for the Z axis (with 2 own motors and own Z limit switches) and everywhere linear profile guides MGN12, but no HIWIN but good (hopefully) Chinaware, where the balls will be exchanged against hardened balls from carbon steel.
Print area will be approximately 300 x 300 x 285mm, print bed 300x300x8mm alu plate (finely milled) and 24V 450W heating bed.

Details:

• Controller: Duet Wifi
• Z-Probe: Precision Piezo Orion , NEW Mini-IR Probe
• Hotend: original E3D V6
• Extruder: Titan extruder as Bowden
• Nozzles + Heatbreak: partly E3D, also from MICRO-SWISS
• Power supply: 5VDC / 50W + 24VDC / 750W-Net line + Opto-Relay -> Duet's PS-ON function
• Belts: Gates HTD3-9mm fiberglass
• Stepper motors: Nema 17, Z: Model 17HS19-2004S1 (1.8 °, max 2.4A), CoreXY: 17HM19-2004S (0.9 °, max 2.0A)

now it's time to optimize …

Below I want to show you what I have created in the last few days with the DueUI.

DueUI is certainly not a replacement for DWC, but for me the ideal basis as a control panel directly on the printer.
Small netbook (without touch) was ok so far, but the operation with mouse pad was not so comfortable. Also the picture quality was not so sharp.

Desire was as much control panels by touch on little surfaceas as possible and not to lose the overview - so actually a contradiction.
Since my 10 inch tablet only serves once a year as a navigation tool on the boat, it has now got a great job again

Surely everyone has it's own idea of ​​what an ergonomic and clear surface is, but with the DueUI you can quite well realize your own taste.
With a little bit of logical thinking, even a non-programmer like me can do something with it.

Below are a few pictures of my current state in the Chrom-browser:

Display in normal mode, axes homed, ATX ON

ATX OFF

And now in full-screen - and now the status indicator is visible

After a reboot - axes not homed and ATX OFF

Open selection menu

The operation of the axes with the jogging as a cross is closer to reality, but so the place is much better exploited - we are all professionals and come so synonymous with it

If you are interested, I will gladly provide the configuration file, but without any guarantee and with the note that certain details are adapted to MY printer and probably only usable on a 10 inch tablet.

i forgot the plan

My new designed surface of the DueUI:

video of my new DueUI surface

Check your M558 if it is correct in your config.g -> H0 ???

I can only tell you how it works for me and it does it without any problems:

• First I have homed my printer in all axes, where I have the endstops X min, Y min and Z max -> so my config.g = "M574 X1 Y1 Z2 U2 S1" (is built differently for you, so configured differently ). also i do NOT use my mini-ir as z endstop

Then I determined the distance with the procedure

• drive the bed to center and Z about 10mm -> check indicator "probe" in the DWC (must be 0!)

• manually move carefully in the direction of Z0 -> display "probe" in the dwc must indicate a value of about 465 when the nozzle come closer to the bed

• drive further in the direction of Z0, the "probe" value must indicate about or over 535 (now your nozzle has only a little distance to the bed)

• drive the bed back to approx. Z10

• Send M558 P1

• send G31 P500 Z1.0

• manually push the printhead into the middle of the bed

• manually approach Z0 with paper

• set Z0 with G92 Z0

• drive to bed position with G91 Z5

• take the measurement with G30 S-1 (note: this value should be between 0.5 and 2.5!)

• now send G31 P500 Zxxx (xxx= the value which is shown at the G30 S-1 command and write it in your config.g too!)

• write the corect M558 in your config.g

@devleon but of course!

Please, urgent attention:

• I have adapted it to my samsung tablet with 10 inches in landscape format

• some of the stored gcode is only functional for my printer

• some tabs show the same info, but in another view (taste)

• some things are currently still doubly and not completely -> it is urgently still necessary to make their own adjustments

• no guarantee!

have fun:
0_1551786964733_dueui_config.gcode

!Rename the file to: "dueui_config.json"!

Now I could access my home network, below the files:

Attention, individual settings:

• Limit switch X -> min, Y -> min, Z -> max
• Installation of the two limit switches as Z-MAX and and finely aligned, so that the separate positioning (line 13 in homez.g) is not necessary for me - but can be aligned in the line exactly -> thus is an automatic heights - Alignment of the two nuts of the ball screw (Z-axis) given.
• Assignment of the two limit switches see my wiring diagram as already posted

@deckingman : My first priority is definitely a perfect backbone of the mechanics.

My guides (mgn12) and ballscrews are aligned with dial gauge (parallelism and flatness) and it is paid attention to a clean and easy running.
The print bed (alu fine milled 300 x 300 x 8mm) will be resurfaced on a flat grinding machine before installation , etc.

All measures usually do not require a software correction. However, I would like to apply the procedure, which also is used in tool setting measuring machines.

Why? just to learn for me.

Of course, my baby is supposed to print someday, my granddaughter is already waiting for the first figures and a personal name tag for her schoolbag. But the current stage is used to craft, build, rebuild, annoy if something does not work and look happy when it works - and learn.

The aim is to create a mechanical system to look behind the scenes, the machines I've just used. These are the last 25 years of application development on injection molding machines, from whose evolution in the direction of electric drives my curiosity comes.

Conclusion: I do not always and absolutely necessary have to use it, but I can do it (such as your "Dynamic Force Canceling" which is very interesting and implemented great)

PS: Sorry for any grammatical mistakes and wrong expressions - my english is only as well as google translators allowed

FileZilla works for me with the following settings:

• Tab General: Encryption - Only use plain FTP (insecure)
• Tab General: Logon Type - Anonymous

@gtj0 I like to share the config file, here it is:

dueui_config.txt

Attention:

• Rename the file after download -> make a *.json file from the *.txt file
• The positions are optimized on my 10 " tablet and may not fit on other screens.
• Furthermore: all the buttons deposited commands and values and arrows are necessary to my taste -> own adjustments.

... and you are welcome to link the video

The only thing I miss at the moment is the display/value of the extruder. Otherwise I have to work intensively with it first.
