- doing preparations for the MakerFaire Hannover this weekend where we exhibit some OSE(G) projects
Tue Aug 15, 2017
- mounted EndStop to testrig
- EndStop
EndStop mounted to testrig
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
- sended package with new pcb to Marcin
- 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
- uploaded firmware on GitHub repository, see [8]
- summarized possible improvements on the signal quality on the discussion page at [9]
Tue Jul 18, 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

- the pcbs of the cap-sensing TorchHeightCTRL have arrived. Perfect quality.
Pcb frontside
Pcb backside
- 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
Ordering page at Aisler
Detailed views on each pcb layer as Gerber file

- 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.
