This is a bit OT for this thread (apologies in advance). Since this is a TriQ thread there is some tie-back to the original subject (i.e. you can use your TriQ block with the Estlcam touch plate operation)
When I installed the Estlcam package I could not help but notice the EULA that popped during the installation dialog (it's small size I found interesting, and it was German). I decided to run it through a translator and was even more pleasantly surprised... As a developer of wares, I appreciate guys who have created innovative and novel software with very reasonable terms and costs...
Estlcam can test all free.
The paid full version you must use for private use on all computers that belong to yourself. For commercial use the license per workstation is valid.
I (the author / Christian Knüll) exclude all liability for property damage, personal or pecuniary damage which may arise directly or indirectly from Estlcam.
I strive errors and problems as far as possible to fix and look forward to corresponding notes, however, the accuracy and usability of the software can not guarantee.
From CNC machines depending on the type and structure of some significant risks emanate. In particular, when using Estlcam for controlling a machine must be ensured that your machine even in the event of a malfunction of Estlcam still complies with all safety and other requirements.
I assume that you own all necessary skills that are necessary for safe installation, commissioning and operation of your machine or you fetch qualified assistance if in doubt. Remember that Estlcam small CNC milling was developed in amateur and semi-professional and is not suitable for controlling industrial machines.
I have no control over how and with what components to get your machine eventually build it - all instructions and examples on my part can only serve as a rough guide and not replace expertise, especially in terms of safety and other regulations.
