Havent done not much meanwhile. Z axis is projected and details milled out. Made it from 15mm thick 6082 alu sheet with 50x20 reinforcements to minimize deflection.

And other free time what i have after dayjob, is gone for building complete new dust extraction system with one big central unit instead of small blower on each maschine.

As promised some more about new dust extraction system. As i earlier posted here idea is to vent that air what is coming trough dust extractor filter outside. For that i ordered special bags made from pvc tarpaulin material. Those bags are over dust filter bags and have output for air what is vented outside. Outputs are behind bags, trough wall and not visible on picture.

Now i have clean workshop air .No extra fine particle dust on air.

Blower is Holzmann ABS 5340P. It has 5hp (3,7kw) motor. It has huge suction power, and already on first tests was clear, that this is way too much. I installed for blower fan speed regulating VFD (Invertek Optidrive E3). On blower fan speed 1800 rpm it has enough suction power to serve 1-2 125mm pipes together (main pipe is 250mm).
That blower running on 1800 rpm is unbeliavably quiet. When smaller units are screaming on high rpm, then its working sound is comparable with cordless drill.
Shortage is, that on colder days is workshop colder due air exchange and needs more heating power, especially when dust blower is running long hours. But spring is around corner and that isnt problem anymore

System to keep the lungs free of dust. Very good idea. I wear the little white masks, when I am cutting and sanding. It is amazing how dirty they get. Thank you for the posting of pictures. You guys are inspiring to me.

I suggest to buy instead of those scrappy white masks 3M half facemask. Example: https://www.pksafety.com/halfacres60s.html or https://www.pksafety.com/3m-7500-lea...tor-combo.html and fine dust filters https://www.pksafety.com/3m-p95-filter.html for them.
Dont buy it over internet. Go to store and find put what size / mask fits perfectly with your face. I have both of them what i linked, but 7500 series fits better to my face.
They wont leak between face and mask like those white masks, and end of dusty workday there is huge difference how much dust have you on your lungs. Of course those white ones are better then nothing, but..... they are quite poor.

Completed today Z axis. Flex buy pressure applyed one hand, measured on spindle bracket is about 0,08mm. To comparision, applying same force on #38 z axis i can bend it almost 1mm.
More pictures about it:

Awesome job

Your z looks awesome and sturdy, good for cutting thick materials.
Today I use my new mask like you suggested. I breathe good. .

2018-04-08 12.06.30.jpg
And today started assemblying spoilboard.
2018-04-08 12.06.19.jpg

I having some kind of problems with those Leadshine closed loop steppers. They are making sometimes weird noises, and if i rush them drivers are getting very hot. I wrote to reseller, seems what they answer. But i hope that i did not buy for 2000 euros pile of crap instead of high end steppers.
Running on 10000mm/min

Running on 8000mm/min

There isnt even no possibility for bad contact etc, because i did not use connectors. Wires are soldered together.

First test cuttings made too:
2018-04-15 16.49.38.jpg
Bought from ebay tool setter for Z axis. https://www.ebay.de/itm/IP67-CNC-Aut...72.m2749.l2649 Repeatability is as promised. 0,001mm. I added this upgrade to #38 too.
2018-04-15 17.13.41.jpg

Still having problemis with motors. Lowered driver current settings, as Leadshine reseller suggested, strange sounds are disapered, but now i havent any power anymore. It is able to move max 6000mm/min, higher speeds stalling problems appear. On same time drivers are coing very hot. Everything what is possible to test is tested, even took computer, smoothstepper and BOB from #38 to be sure that problems arent on input signals to drivers. Now ordered one more motor -driver set what is tested for Leadshine Germany reseller and is working. When it arrives can i go on and find out what is causing problems.

Got on friday new and tested driver-motor set. With new driver everything seems to work fine.

Motors stalling due too large postition difference, it was able to move max 8000mm/min, stalling on 10000mm/min :

on 75% current setting extreme jerky movement, but due encoders and closed loop system there is no position loss on stop:

Installed new driver and now i am able to move axis 20000mm/ min and more without any problems:

Now i am waiting what Leadshine reseller is answering.
