Edmund do a similar one which is half as thick and is nearly £13 + shipping... Seems a lot for a tiny mirror! If anyone knows of an alternative source, that would be good to know Louise After all that I've had a second invoice from Thorlabs for the short-shipped mirror! Not very economic to separately ship a single 0.5" mirror but I think I'm happy! At least I don't worry about where to get one from now.

dyfiastro Posted November 10, 2019 Share Posted November 10, 2019 Hi everyone After finally getting my 3D printer built and "Tweaked" over the last few weeks I am now at a stage where I am happy with the prints and was wondering if there are any interesting projects that around. I am in the process of printing out a solar finder ready for tomorrow and designing an electronic focuser housing for a mak 102. Would be interested to hear what everyone else has come up with. The printer is an Ender 3 Pro with BLTouch and a replacement SKR Mini E3 v1.2 Board. 2 Link to comment Share on other sites More sharing options...
Thalestris24 Posted November 10, 2019 Author Share Posted November 10, 2019 What are the 'BLTouch' and the SKR board? Louise Link to comment Share on other sites More sharing options...

Louise A BLTouch is an auto-leveling device. it will compensate to a degree for a slightly uneven bed by taking measurements at various points and then using those measurements along with a Z-Offset to correct for it. You can also use visualisation tools using things like Octoprint to visualise how level the bed is. I have Octoprint running on a rpi so I can send prints over the network to it and also directly from cura. The SKR Board is a 32bit replacement board for the Ender3 (The standard board only has an 8bit processor). Amongst other things it has upgraded TMC2209 stepper motor drivers. The difference in sound alone is enough to make the upgrade, the loudest part of the printer now is the fan. It also negates the need for TLSmoothers and dampers. The board Runs Marlin 2.x as well so there are a number of additional features. Edited November 10, 2019 by dyfiastro Link to comment Share on other sites More sharing options...
Gina Posted November 10, 2019 Share Posted November 10, 2019 There are lots of threads and Blogs on here describing various things people have printed. Plenty by me too - astro stuff and clocks as well as making 3D printers themselves. Link to comment Share on other sites More sharing options...

Oh ok, mine does sound like R2D2/morse code ha ha but I quite like I I just have an otc Ender3 Pro but it does what I ask of it. I've no idea what Martin 2.x is either...

The printer is located right beside me when I am at my desk. I also could not believe how loud it was at 3AM in the morning. Marlin is the firmware which many 3D printers including the Ender 3 run on. Once thing to note regarding the ender 3 in its stock form is that they do not enable thermal runaway protection in their firmware. One of the first things I did when I got mine before upgrading the board was to load a bootloader and modified firmware onto the board to enable a few things including thermal runaway protection.

Flashing the firmware to either the updated "Vanilla" Marlin firmware which creality base theirs off or others that can be compiled and installed sort this issue out Link to comment Share on other sites More sharing options...

They have enabled thermal protection but not set it up correctly and some features have not been enabled. The basic setup is there but not effective. Most places recommend that the firmware is updated for this reason. If you have a version of the ender 3 that has a bootloader then its a simple case of compiling a new firmware and uploading it. If you have a version without a bootloader like my new ender 3 Pro then you have to use an arduino or flasher to burn a bootloader first so you can then update the firmware Edited November 10, 2019 by dyfiastro Link to comment Share on other sites More sharing options...

Gasman Posted November 10, 2019 Share Posted November 10, 2019 Hugely interesting post 👍. As an (admittedly not very active at the moment) spectroscopist using an Alpy 600, the mention of the Lowspec has stirred a somewhat dormant interest in spectro for me and with the addition of 3d printing adds yet another level for a self confessed gadget dabbler like moi!. Would the Ender 3 pro suit a very novice 3d'er ? A birthday is imminent so the time might be right😁. Cheers Steve Link to comment Share on other sites More sharing options...

dyfiastro Posted November 10, 2019 Share Posted November 10, 2019 I think on the stock firmware there is a about printer section in the menus. this may well give the firmware version Link to comment Share on other sites More sharing options...
