Finally fixed that issue... Printing again..

Except now I'm printing things for the missus, so maybe it sjould have stayed broken

Yeh, kinda annoying when the SO's start realizing the potential - I'm busy printing planters (Robert) for the bathroom.

Spent most of yesterday trying to figure out why my printer was under extruding - checked for blockages, etc, couldn't find the issue, this morning I had a shower moment and realised I updated the firmware and hadn't set the e-steps.

Those damn e-steps gave me huge grief because when I bought the printer I swopped the plastic extruder for an aluminuim one and it changed the steps from 93 to 97.3

Oh, and if you are compiling your own marvin, you can set it in code before build. @ToxicBunny , you should check out tweaking your own firmware, pretty fun.

So far I'm ok with the stuff she wants me to print, since it will be for her Cricut machine which I have plans on abusing in the near future anyway :)...

Nice to have a vinyl, etc cutter in the house as well as a 3d Printer now..
Next investment will be a CNC machine and then my "maker" ability will be somewhat complete for a short while.

Yeh, using jyers, but also changed my extruder - but mine goes from 93 to 140... so having it back at 93 was a big issue.

I've got a Cheap Chinese printer off Gearbest a couple of years ago and it has served me well. I did the PLA and ABS expidition, Which is all good. Now how does Resin printers compare in strength vs ABS and PLA? I print Mechanical creations for myself as a hobby and when I get bored. Gearboxes and gears specifically. ( learning to Design those was an Experience on it's own...)

My understanding is resin is good for high detail in small sizes. But strength wise, not sure, I think there is a resin called ABS like that has similar properties to ABS which is the most common plastic form out there.

Generally if I want strength I still prefer FDM prints, especially at larger sizes. Depending on torque etc. smaller functional parts could be really nice on resin - you'll get great quality and can print multiple parts at once but they will be more brittle than pla, tho this might not be an issue depending on how your gears are working. There are engineering resins but for most use cases the additional cost doesn't really warrant it when a regular pla print will do the job.

Can probably print a few small parts for you if you want to cover shipping to see what its like.

You get very strong resin and filament but the price for resin is still quite steep so its better for final parts. Hopefully the prices come down as they became more popular.

Hey all,
Any suggestions where I can buy some 3D resin in clear/transparent red?
Tried most of the usual stores, but no luck so far. A 0.5L would be fine.

Someone suggested using clear resin and adding red 3D colour or pigment, would that work? Or would it go cloudy/unclear?

Think it would depend on the strength of your tint? That's basically what you would be doing.

Food colouring?

If I look at the ratio of 3D magenta pigment to clear resin, it should be 100g resin to 0.82g of pigment to get a good red transparent colour. Never used pigments with resin before. Only used gray resin for prints to date.

Not sure about food colouring option...
