Nice render you have there... :-/

Is anyone else tired of seeing people showing off CAD models of printers/CNC machines? Like, yea! Great! Does it work? Are you ever going to make it?

Yes, I'm guilty too, I never made the below printer out of 40x40mm extrusion, it's pretty stupid.

I'm loving that the parts available to us now mean we can pretty much arbitrarily nail together working machines out of well tested off the shelf parts. I.e. this extruder on this nozzle under this electronics in some frame I'd like to try.

But seriously, we see so many models presented like finished products and so few actual machines. I'm all for requests for comments, it can only serve to help one or all of us.

Am I being an unreasonable misery guts?
Borrowed your extrude scad files.

There is a free event in Southampton on Monday.

A professional technician is on hand at the Southampton Makerspace every Monday to help your repair your bike, teach you how to repair your bike or just talk about bikes.
My Journey Southampton and SoMakeIt, a non-profit Makerspace, will be hosting 'Bike Kitchen' every Monday.

Southampton Bike Kitchenis an open DIY workshop where you can work on your own bike, and learn the skills necessary to fix it in the future, rather than pay for someone else to do it for you.

We will be running drop in sessions every Monday from 7pm-9.30pm, where you can come by anytime and work on whatever you like.

There will always be a mechanic on hand to answer your questions, provide you will help and advice, along with a range of tools and stands for you to use.

Here’s how it works: You fix your bike yourself, with help from volunteers. You can use the space, equipment, and on-hand instructional assistance for free.

It will offer a low-cost way for Southampton cyclists to keep their bikes in good condition.

Southampton Biciycle Kitchen will open every Monday from 7pm - 9.30pm starting on the 8 February for drop-in bike maintenance sessions.

Makin a 'space.

This was nearly a year ago, feels so much longer.

Thinking about the problem of peeling.

So far my exposure to SLA printing is that I once spent an afternoon with a Form1 and it's owner watching prints fail by peeling off the bed rather than the tray.

I wonder if a transparent liquid more dense than the resin, but that does not mix could sit in a thin layer below it, keeping the resin off the tray?

PLA works very well, although this orange from Spectrum is very inconstant diameter and very under-size. Have noted a recommanded thickness to use with Slic3r on the side of the roll.

Taz is back! Printing ABS through an E3D v6 nozzle onto PEI bed.

Next up, try PLA. Maybe NinjaFlex later to see if it can do it.

Sourced a PEI sheet for my bed, printing Lulzbot ABS @ 245C onto the bed @ 85C with no brim, 100C with no brim and then 85C with a brim.

It's very good, I think this will let me lower my ABS print temps. Parts just snap off when the bed is cool. Next up try PLA.
