I’m having first layer adhesion issues – which is commonly caused by poor levelling on these things
Could also be a number of other issues but I’m confident I can get this resolved next week
The major fault on this one is that the bottom row of keys is all squished going to the right hand side, due to that side not adhering to the build plate correctly.
Have had another print literally just finish – with adjustments and that’s also come off the build plate so I’m really confident that I just need to try re-levelling again!
Apolgies for any delays and people waiting on keycaps….
I believe I may have reached the end of life of my original Photon Mono printer. for the past couple of months, i’ve been having more and more print failures, and have had no idea why. I’ve approached the problem analytically to figure out what’s wrong
Where it started –
I had a proper working file that ‘just worked’ – exposure about 35s for the first layers and about 1.8s per other layer
That started failing a bit. some keys were printing incomplete. I increased the exposure slightly and success again.
More fails, this time the first layers were coming off the build plate. I increased the exposure for the first 4 layers and success again.
had many minor creeps of fails, up to now where i’m at around 50s for the first layers exposure and 2.2s per layer.
I figured maybe the temperature in the conservatory is too low – Nope, iterating a bunch of exposures with the printer near the radiator in the living room also had nothing but failures.
So, after a good 15 fails in a row, many caused my me experimenting with extremes, i’ve given up with the photon mono. There’s many things it could be, but I’m thinking it’s feasible that the LCD has finally ‘failed’. I’ve easily gotten 1500 hours of actual print time on the thing – well over 1000 will be just the production keycaps at 6.5 hours each!
I’m dialling it in to start printing the keycaps. First one’s going right now (50% UV power, 3.5 seconds exposure and 45s base layer if you like to know)
IF this keyboard prints – fantastic, I can print two at a time in just 5 hours! i’ll be through the backlog in no time 🙂
Thanks for listening and sorry again for the delays!
