UPDATE: 19th June 2016
Just to make anyone aware - over the weekend my images were used in a couple of 2.5DXL frame listings on AliExpress by two sellers. I did not give consent or permission for my images to be used, and my images even show missing items explained below(!!). The sellers have since removed their listings, but in case of future repetitions, I DO NOT GIVE PERMISSION TO USE THESE IMAGES FOR COMMERCIAL USE.
Finally got my P3Steel frame cut and picked up. Material was 3mm mild steel, laser cut using the provided CAD drawings as-is. Surprising heavier than I thought it would be, but this gives me confidence that it's going to be rock solid as mentioned in other builds.
Images show the frame as delivered by the steel works where I got it cut. It came very clean, straight and not at all flexed or bowed by the thermal cuts. Not sure how it was managed post cutting, but the burs usually left on parts CNC'd were filed off or not there, which is great. Going to start on the sanding and paint prep (matt black), then begin the build! Hopefully a video log of the build should be on my YouTube channel eventually! And a more detailed log on my personal blog Chunky Media.
Couldn't resist dry fitting the parts to see what it looks like, and i'm very impressed!
One note to mention so far - the mounting holes on either side of the printer on the upright "triangles" are NOT identical. If you find your Arduino Mega mounting holes do not line up - you've got the wrong side! Not sure if this was intentional, but worth noting, as apart from those holes they are mirrored parts.
There is one piece missing in the images - one side of the y-idler housing. This has since been delivered - but you get the idea!!
I would like to make a remix of this frame as a "Toolson Edition" such as "2.5 DXL-TED" which would re-arrange the parts and remove the x-axis bearing clamps and the y-idler housing. As most steel cutting is worked out on how far the laser travels while cutting it would be good to do away with these parts which aren't required on the Toolson Edition - and thus bring down the raw costs.... one day!
