Let me start by saying that I have a Basic machine, from the Pre-orders era, and it’s been sent in for repair once, and also had the black cable replaced.
I bought a Plus a while ago and i’ve always had it as my “Cutting Machine”. I let it do the wood cutting because it’s supposed to be more powerful. It has served me well and still does great with most of my cutting jobs.
Maybe 2-3 months ago, when things were heating up weather wise, my Plus settings that i’d been using for a long time on many different pieces of wood stopped cutting through. I searched on the forums here to find a reason why and maybe a solution. I did all the lens cleanings, I do auto focus on my material, I checked in with Glowforge support to see if it was a hardware issue. They said as long as it cut through the PG material, then it was doing alright (I can’t really argue with them there).
I also read up on here about humidity and how it can affect materials and the machine performance. I’m in FL so of course, humidity never wants to leave you alone. But my machines are in an air conditioned office. Still, I said maybe it’s the humidity and maybe it got into all my materials. Things have been cooling down here, so maybe that will have an affect later down the road.
I digress. The reason for this post is that I’ve been testing the same pieces of purple heart on both my Plus and my Basic, and the Basic is actually giving me cleaner and more consistent cuts than the Plus. Same settings. I’ve tested several different pieces of purple heart just to see if anything changes. I’m very confused! Can anyone help me out by explaining why this might be happening? The Plus has a stronger FP than the Basic right?!
EDIT: Uploading a photo to kinda show what i’m talking about. The left is the Basic’s Purpleheart cut. The right is the Plus Purple heart cut. This is a consistent result.
