@wilriker said in Need advice on new heated bed aluminium plate:
who needs PEI on the side where the heater is attached anyway?
Lots of people use these plates on top of the heated alu bed (with clamps). It is nice to have a plate that you can turn over to choose between a glossy or a matte finish.
That actually makes sense, and I think it might be the cause of some problems I am having when printing smaller layerheights. I do not have the luxury of so many microsteps (Duet 0.6) but I makes me think if it is not better to go the absolute extrusion way instead of relative. I have read, long time ago, that relative extrusion was the preferred method, but I lost the "Why?". Maybe someone can shed some light on this.
@Phaedrux Yes, but I think the difficulty is getting no air trapped in the glue-liner. It expands when heated and causes the issues like unevenness and will work areas loose eventually. I have a glass plate and a 6mm alu plate both with thick PEI glued on top. I am very happy with how it sticks, but absolutely NOT with how even it is. I am a trained signmaker so I know how to prevent airbubbles and I have none visually, but nevertheless it's uneven enough to spoil first layers.
@deckingman said in Baby Stepping.. can it, or can it not be permanent?:
I'm just trying to understand why people want something that has to be changed regularly to be made to persist or be permanent.
I do see the value of the suggested feature. Especially for values that change regularly. I find myself babystepping down a bit for each print of the roll I am currently using. Yes, I need to compensate for that in the H parameter of G31 command, but call me lazy! (does everyone has to lookup if it needs to be added or subtracted?). What's wrong with a button that sets the default height compensation in config.g based on the currently set babystepping? I would like it for sure!

I wonder how much of the precious memory on the duets are used for features that are catering to people whose printers are so poorly built that they need to calibrate it every single time they print. How much of the development time put into RRF was for such features?
Babystepping works as it does now. Config-override exists for you to save settings, but not babystepping. Figure out a way to save your babystepping values with that you have now!
It's so frustrating that some of us jump through hoops, spend tens of thousands of dollars or euros, build a machine that is rock solid, but yet we have to deal with the onslaught of features and feature requests from people who can't be bothered to edit one line in one file?
We should not cater primarily to the lazy folks who can't be bothered to perform extremely simple actions.
A little respect please... Not anyone uses their machinery the exact same way you do so yes, other people have to be catered too. The suggested option is a nice one, even if you do not understand that. RepRap is supposed to be the most userfriendly firmware, no?

Scenario 1. With baby stepping as is (non permanent), you start a print, then adjust baby stepping. Repeat for the next print.
Only if you are homing again you will have to readjust. Making it permanent you do NOT have to readjust.
Scenario 2. With "permanent" baby stepping, you start a print, then adjust baby stepping, then save it. But you still repeat that process for the next print because you say "I find myself babystepping down a bit for each print........"
I find myself babystepping down for each print, because I cannot make it permanent. You have it the wrong way.
So all you are doing in scenario 2 is saving the value that you are going to change anyway next time you do a print. Why?
No, I do NOT need to change anyway if my value gets permanent.
I think you need to look at it not as permanent babystepping, but as an easy way to dial in the H value in config.g. Nothing is easier then looking at a result, adjusting, looking again, and when it is spot on, press the button and it is set. After pressing the button, babystepping is at 0 and no need for adjustment until you change material, adjust flowrate or esteps, or do something else that requires evaluation of your nozzle offset.
