Just wanted to show my printer scanning one face of a coin.
I uploaded the scan on Thingiverse: https://www.thingiverse.com/thing:3366129
Here's a video with it in action: https://www.youtube.com/watch?v=9lPobTaEvIE
It scanned at 0.15 mm grid, about 42,000 points, and it took about 8 hours to scan.
I made a program in C++ that controls the 3D printer through Telnet over WiFi (using Duet WiFi). The program exports 2 files, one point cloud XYZ file, and the STL file.
@phaedrux said in 3D scanning a $2 coin with 3D printer and DIY touch probe:
That's really cool. How does the touch probe work?
It's actually quite simple. 3 sets of switches that are wired in series. A spring pushes the contacts so that the current goes through when the probe does not touch anything. When the probe touches something, the current is interrupted.
Here's a touch probe I found on thingiverse: https://www.thingiverse.com/thing:721620 I am sure you can find many others.
Here's how I made mine:
Everything is from stuff I found around... washers for contacts (no clue what size, probably washers for M4 screws i think), PCB prototyping board (4 cm by 6 cm), 2mm and 3mm copper pipes (from local hobby shop), M2 screws, spring comes from BL-Touch kit, and finally a small sewing needle. I tried to find a small, but thick needle, because the longer it is (or thinner), the more will bend when it's touching. If you need to scan deep things, then make the pipe longer.
The sewing needle goes in the 2mm copper pipe, and with pliers I squished the pipe as hard as I could to grip the head of the needle.
Hi dc42,
Yes, I do have the deployprobe.g and retractprobe.g with M280 gcode in those files, but the problem is that I need those files because I also have tools for 3D printing, actually I have 8 tools in total:
I use BL-Touch on the first 6 (first 4 the BL-Touch is in front, the next 2 are in the back so they are obstructed in this image), number 7 is a touch probe (for 3D scanning), and last one is the milling motor that I am trying to use now.
@ander , I made all my videos private, but I forgot I had those 2 videos shared here, I made them public again

New Update:
When I issue command "M109 S100" it works! it's heating up!
But! when I select the temperature from the drop down menu in DWC, it does not work!
What M code does DWC send when selecting a temperature ? how do I edit that ?
Since my previous post, I also tried to connect to OUT 2 and changed "M950 H1 C"out2" T1", and it still did not work.
To make sure that my heater is OK, I connected the heater wires directly to 12V of my power supply, the heat was going up pretty fast, and the DWC was showing the temperature going up also.
Forgot to show my board firmware in my previous post:
FIRMWARE_NAME: RepRapFirmware for Duet 3 Mini 5+ FIRMWARE_VERSION: 3.4.5 ELECTRONICS: Duet 3 Mini5plus WiFi FIRMWARE_DATE: 2022-11-30 19:41:16
Please help! i'm out of ideas
I don't know what is happening, I plugged the heater in the "OUT 1" but the Duet 3 is not giving power when I set a temperature in the DWC.
I measured the wires, it gives me 4 ohms (when the printer is off).
I turn on printer, and set a temperature, and I measure for volts, and nothing, 0 volts.
Here are my settings for the nozzle heater:
M308 S1 P"temp1" Y"thermistor" T100000 B4138
M950 H1 C"out1" T1
M307 H1 B0 S1.00
M143 H1 S280
The thermistor works because it shows room temperature, and when I heat the nozzle (with a soldering iron for example), then the DWC shows the temperature rising
I'm tying to setup a static IP because almost every time I turn on the printer it gets new IP.
I entered this in the config.g
; Network
M540 P0xCE:0xAF:0xAA:0xAC:0xFC:0x38 ; MAC Address
M550 P"Printer400" ; Set machine name
M552 S1 ; Enable network

M586 P0 S1 ; Enable HTTP
M586 P1 S0 ; Disable FTP
M586 P2 S1 ; Disable Telnet
But it does not seem to make any difference, it still gets a random IP
For M581, I just could not get it to trigger with exp.e6stop on the Duex5
; Configure external trigger - big red button
M581 P"^exp.e6stop" T0 C0
So in the end I unplugged the wire, and connected it to zstop, and now it triggers, BUT!!! once triggered, I don't know if it keeps triggering, or not being able to connect back, because the only way to get my printer working again, is to power it off, and back on. This is the command I am using:
; Configure external trigger - big red button
M581 P"^zstop" T0 C0
For filament sensing, I still did not get the chance to test it, but I changed it to:
M591 D0 P7 C"connlcd.3" S1 R50:150 L0.305 E5
Hoping that it is correct.
For Camera logical pins, command M42, I can't find a chart or something with the equivalent pins.
This is the old chart I used:
https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins#Section_Duet_2_WiFi_and_Duet_2_Ethernet
I can't see the pin names "GPIO pins 1-4" in here:
https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet
For M42 P62 S0, I think the pin name is "spi.cs7", right?
I Fixed endstops, Z-Probe, Fans, Heaters
I changed M581, but does not work, it does not trigger.
Filament sensing, changed but did not try it yet, I don't know if "e10stop" is correct
For Heaters, I have no idea if I put the correct numbers, but it seems to work

I'm done for today, I'll try to fix the rest tomorrow. In the mean time, if someone could take a look at my new code and let me know if you see some problems?
Thanks!
I don't want to downgrade, I want to make my printer work with the latest firmware
I didn't upgrade the firmware for a long time, last one I had was 2.02(RTOS)(2018-12-24b1)
Now I have:
Board: Duet WiFi 1.02 or later + DueX5
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.01-RC1 (2020-02-08b3)
Duet WiFi Server Version: 1.23
BLTouch does not work anymore, extra fans don't work anymore, tools I think I have a problem there too
BLTouch is connected to Z PROBE IN, and PWM5 (E6_PWM) on DueX5
I have to extra fans on Fan1, and Fan3 on DueX5
Fan 1 seems to work, but it's either on or off, and Fan 3 does not work
For tool, I have 6 tools that I can change on the printer, so I define that in separate macros, but I want to setup a default one named "NO TOOL" to let me know that I have to select a tool from a macro depending on what tool I have attached to the printer. In the macro I override previous tools
I am new to rrf 3, I tried to search the new way of doing things, but I am having a hard time
