- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.
- EndStop
TorchHeightCTRL-D3D Hybrid
For a D3D printer i still have to add the motors, an extruder and the heatbed, but as a testrig for the TorchHeightCTRL its ok for the moment.
The UniProKit, my modular construction system
The OSE Germany stand at the makerfaire; the red box contains an experimental setup for my zinc air fuel cell project, where we are "burning" (oxidating) zink into electric energy and show how the zinc can be regenerated then by renewable energies.

CloseUp
- implemented EndStop and homing-functionality into firmware and uploaded latest version on GitHub [1]
- performed testing for homing and switching between manual and autobalance-mode
- added testing-video on Youtube: [2]
Tue Aug 08, 2017
- implemented button-pressed functionality into firmware [3]
- added more detailed pinouts to wiring description [4]
- made a wiring diagramm for RAMPS_to_TB6600
How to connect the Pololu-stepperdriver connectors on RAMPS with a TB6600 driver
Tue Aug 01, 2017

- made wiring-diagramm and BOM and added it to wiki-page
- made a list of checkpoints when starting from scratch with the new pcb [5]
Mon Jul 25, 2017
- added Host-Monitoring-Tool ad7747mon Processing-Sourcecode to GitHub repository, see [6]
- added Video showing the first auto-balance testruns, [7]
Sat Jul 22, 2017

CNC_Torch_Table_Z_Height_Control - working on code for auto height control.
Tue, Jul,11,2017
- made sensor-head and mounted it on test-rig
- wrote monitoring-programm (in processing) for visualizing CapSensing-data
- first test-samples measured on the test-rig with new sensor-head, see video [10]
sensor-head made from 2.75mm copper wire, outer diameter 42mm, inner diameter 32mm
whole sensor-probe with shielded coax-cable and BNC-connector
Experiment1: moving probe along 10mm in steps of 0.1mm
Experiment2: moving probe along 50mm in steps of 0.1mm
Experiment3: moving probe manually along 50mm in steps of 10mm ==> 5 distinct plateaus. Those little peaks on the beginning of each plateau are artifacts, resulting from moving the carriage by my hand.

- soldered 3 PCBs
- testing circuits, all seem to work basically
- checked for firmware in Aidan Log from 2014; use the latest firmware-version from him
soldered SMD parts
added ThrougHole parts
made 3 PCBs
added Arduino Nano
first test-rig, utilizing Osci-probe as sensor
measuring against a copper-plate, grounded by crocodile-clib

- made progress with printing and assembling 3D-parts for the universal axes for a D3D printer. I have meanwhile printed all parts for the raw-axes and started assembling them.
Parts for the raw-axis, 3D-parts made from ABS
4 axes assembled, incl. Idler
Motors, pulleys, belt and endstops to go

- 3d-printed jog-wheel knob [11]
- manually steered height control
Jog-Wheel for KY-040 rotary encoder
- made wiki project page for manual height ctrl,
see CNC_Torch_Table_Z_Height_Control
Mon, Jun,19,2017
- made manual heightcontroller for torchtable, based on Arduino/Ramps and TB6600
- manually steered height control
TB6600, Arduino_Mega/Ramps, KY-040 rotary encoder
stepper driven lineardrive
- demonstration video on youtube: [12]
- made from standard components, nothing to solder ;)
Wed, Jun,16,2017
- completed Mouser part-list and setup project on mouser. This can be accessed at [13] and there you have to type in as project-key 64fff8ecbf
- added exported part-list also to GitHub
- printed more 3d-parts for D3D
Sun, Jun,11,2017
- exported Gerber files from kicad and set up a pcb-project page on go.aisler.net [14], including option to order the pcb. I ordered three, for 36.00 EUR (incl. shipping) in total. production time is about 12 days or lower.
- pcb manufactured by Aisler

- today i received an order from a special material filament named "Iglidur I150 Tribo-Filament" from Igus [15]. This is specially suited for 3dprinting sliding parts and is about 50 times less abrasive than ABS.
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.
