Today i am off to been and queued to buy materials to build and enclosure around my new laser engraver/cutter.
Why been and queued? Cos they will chop up the sheet and its open!
After spending an hour or so putting it together... its only a 5.5w laser "optically blah blah brown smelly stuff ... 20w".
I knew this going in but I just wanted one to play with to see if it was worth spending some decent money on one.
Just a cheapy amazon jobbie, only want one to play with, if I can see more/better uses for it I might invest in a better unit. Just thought it would be a useful addition beside my 3 3d printers.
Mine renews in a couple of weeks and the price they have given me is better than the one they are offering on comparison sites, pleasantly surprised.
Also shocked to see the 4 slightly cheaper ones have quadrupled my excess, guess I am staying with my current company.
Was told that the hedges around school were getting straggly and need tidying up, fortunately I had about 6 hours worth of online training to do in the nice air-conditioned staff room that stretched to the whole day cos of computer problems. :p
Sure I can find some more paperwork to be done...
I have been pretty much printing PETG exclusively for the past couple of years, good prints, nice and strong. I use watered down PVA glue for all types of plastic for bed adhesion and it has never let me down.
I try not to print more than one model at a time as it is impossible to avoid...
I run my petg 240-250C as well anything below 220 and I get layer adhesion issues. Is more stringy than PLA but I have dialed that out mostly, temp towers, string tests, torture tests etc etc, spent a month on it, was tripping over old tests for months...
I rarely have an issue with filaments, usually if i am gonna have a problem it surfaces pretty much straight away. Its usually cheap filaments that I have problems with (as in on offer etc rather than just a cheap brand).
I can do what you need I am just unsure of what it is you are asking. Do you want it set up like a regular mitre box or do you have some specific measurements where you want the slots?
The only times I have experienced layer shifts like that is because I have left something lying around that impedes the head or bed travel causing it to crash and making the belt(s) jump.
Never happened on the last layer though.
I use watered down PVA glue on my bed, everything sticks well on 1st layer, is easy to repair and fairly easy to clean off once the buildup is too rough.
I was in there yesterday ordering a couple of bits, I found the tablet to be soo much easier because it has a search function!
No more flipping back and forth between the index and product pages. :clapping:
Is the face completely flat? I have downloaded some models in past that have a very slight angle on what seems a flat face.
Otherwise I would say model is not flat to build plate.
Are you setting your nozzle height to zero when levelling?
This can cause the issues you're having as the nozzle is never at zero when printing, so if you set your levels at zero nozzle height it will then add the first layer height on top of your paper thickness causing it to be too high...
