Nice idea! Bulldog clips do give a greater holding force than swiss clips if you are using them to stop the glass bending (which only works if you have made your heated bed rigid).by spinorkit - Ormerod
Yes, it starts getting quite heavy though. One mm of glass weighs about twice as much as the aluminium extrusion I put in, and I find it difficult cutting the corners off 4 mm glass let alone 5 mm. Also, I find thicker glass more prone to cracking due to the heated bed, unless you go for expensive borosilicate, I guess. Anyway, tweaking the outer led worked well and hasn't compromised the accuraby spinorkit - Ormerod
Thanks for the photos. Actually, I bought some swiss clips from E3D in the hope they would solve this issue. The pieces of circuit board (which I assume you made yourself) look like they would make them easier to use. The problem is that when I started printing my glider wings (Proteus slope soarer) I noticed problems with the glass bending due to the tension in the print. I discovered this wasby spinorkit - Ormerod
Just wanted to say how pleased I am with your height sensor. No other sensor was compact enough to easily mount anywhere near the hot-end with my fan duct in place. Also, I like printing on glass. To measure the standard deviation of the height measurements from the sensor, I tweaked Marlin so that G30 would output the trigger height to 3 decimal places (1 micron resolution).
