Like that idea alot. At the moment I use a set of different SD cards with different configurations on, eg. 1) Small table- Bowden. 2) Large table-Bowden and 3) Small table-Direct. The trick is to remember what changes you make. Often use a text editor where file comparisons can be highlighted. It works with care but have still made ommissions due to last minute changes. By the way the printer is home made and is constantly being modified.

Just an idea but how about a programmable set of buttons on a bootup menu to select which config to use?

Done.

Excellent, thanks for that.

Hi All
I am experimenting with a geared extruder which has been calibrated to get the step value right. However my second extruder is non geared and requires a completely different step value. Can the different values both be put into config.g, can only see a value for one E?
Thanks for any assistance.

I have a 450mm x 350mm PEI covered bed that has been sprayed on the underside with Matt black fast drying paint. Didn't fancy risking the oven bake method as I get too many burnt offerings from the oven already. The paint I used was from a well known automotive brand and required 24hrs of drying to harden. Being skeptical of the adhesion properties I subjected the painted side to the good old masking tape rip off test and all was good. The PEI is in 0.8mm thick by 10" square sections laid out in a staggered pattern on 3M 468MP adhesive sheets. The sheets were glossy and gave me a few problems with reflectivity and David's excellent IR sensor. A few failed prints later I read about 'scuffing' the surface so got hold of a 3M Superfine abrasive pad and haven't looked back since. PEI has been a great surface for a range of filaments with a few more yet to try.
Apologies for a long 1st post but this controller and the support given on this forum is absolutely awesome.
