* EMC is quite configured. Max-Movement speed is approx 2400 mm/min. Its a great device.
* EMC is quite configured. Max-Movement speed is approx 1980 mm/min.
** Consider not drive this fast anyway - 2200mm/min is currently a good setup without loosing steps
** Consider not drive this fast anyway - 2200mm/min is currently a good setup without loosing steps
** If you use feed-override, please make sure not to run with 1980*1,5mm/min!


* Homeing procedure in EMC is functional, and by that also soft-limits. Its now "nearly" impossible to move over some limits. Start EMC, turn machine on with f1/f2, press "home all", wait 30 sec. Than traverse to the wished zero of your working coordinate system, and touch off in all three axes.

* The Spindle, aka the Kress, is switched on/off automatically.
* The Spindle, aka the Mechatron, is switched on/off automatically.
** This is done with the spindle buttons in EMC. However, on the physikal controller device onboard the geilomat cupboard, the relais switchs have to be turned off.They override the emc settings.
* Spindle speed must be set to a value between 6000 and 24000. Use GCode like M3 S6000
** The Spindle needs some warmup before running. Manual says One minute on 6000rpm, then increase in steps of 6000 until the whished speed is reached. stay for one minute on each level. If the spindle is very cold and has not run about a week double the times!


* Double sided boards kind of work, although its a bit tricky: [[PCB_CNC]]

* Joypad is configured: Buttons 1-4 are increasing feed rate, while the analog sticks are the movement  --[[Benutzer:Bkubicek|Bkubicek]] 19:29, 15. Jul. 2010 (CEST)
* A flat intermediate wood board 30cm^2x1cm, milled flat, now exists. So pcbs can be glued with double sided tape in a completely flat way.
* The dust removal system is configured, and working.

* 1-2 Kress Überwurfmuttern. Das ständige Rausmontieren suckt gewaltig.
* too much ;)
* 2-schneidige Fräserköpfe 2-4 mm 8-20 Schneidenlänge.
 
* Schon bestellt: [[Benutzer:Bkubicek|Bkubicek]] 09:41, 3. Aug. 2010 (CEST) get some Dustbags for Thomas Blue Power, if it can stay permanently, or an industrial vacuum cleaner..

===The big reconfiguration===
between 2012 and now some crazy guys had a vision in their heads that the CNC needs to be reconfigured.
They build a heavy (around 700kg) table and cage and pimped the settings of the cnc. they even installed a HF Spindle for super mega awesome milling.
