To do: Nozzle illumination idea

-

 While working on the NeoPixel fixing on the gantry, I was puzzled by why the first LED only, remained on and white. It wasn't until I was browsing the Marlin code that I spotted this

I couldn't see that this was going to be of any use but then realised that I could split the run of LEDs and have this first one installed for nozzle illumination, separate to the main run on the gantry. So, I plan to add this to the to-do list.

I can fairly easily modify my BL-Touch mount too such that the LED can be mounted there, directed at the nozzle but far enough away to avoid the heat. I just need to include the extra wiring in the harness. 

X marks the spot


I can then reference this LED separately in GCODE to control the nozzle illumination as I need.

Update: delayed but not forgotten

-
Those of you following this blog will have noticed that I've gone a little quiet for a while. This is due to a combination of factors. First, I am very busy with work at present and, secondly, I have a backlog of things which I need to print for jobs around the house. I can't print with the printer at the same time as rebuilding it. To give an update on progress: I still need to rejig the X-axis cable chains to rotate them by 90° The fanless PSU seems to be working very well indeed and makes a huge difference to the noise of the printer The foam insulation on the base of the HBP also seems to help a lot and works far better than I'd expected. Heat up time is improved significantly and excess cooling between prints is also reduced.  I have a set of Z axis pull-rods to install for extra rigidity but these need to be modded to fit the 350mm Z height.  I also really want to move to the latest version of Marlin to address a few annoying niggles which I know are present in 2.0.5.

Update: Mopping up

-

Today I have been working on mopping up some tasks which need do in preparation for creating the cable looms. This latter task is now a little delayed as I've decided to make the stepper motor cables with shielded cables, just because I don't like the amount of noise which they're pumping out .  Today, I have carried out a number of preparatory and remedial processes.  Installed the ESP01 WiFi module into the TFT35 screen. I had had a number of aborted attempts at this previously (it's more than a little arcane) but this time I have managed to get it working. In practice, I may not use it that often but it could be useful in some circumstances. It does seem very basic, but it does mean that I'm not tied to a cable.  I also decided to replace the IGUS bearings on the X axis with traditional roller bearing ones. While I had the carriage apart, I also replaced the heater block, throat and nozzle.  I also upgraded the X axis belt to a high quality Gates one as I'd b

SKR1.4 and TFT 35 - using long file names and print from SKR SD card

This is a bit of a diversion from the rest of the blog, but it's relevant as it's on the same path. I felt it might be helpful to post this as I'd tried, unsuccesfully, to find a definitive answer elsewhere so got there by trial and error.  If you have an SKR 1.4 mainboard coupled to a BTT TFT35 (NB I suspect that this will also be relevant to other combinations of MB and TFT) and want to Enable long filename support Add the MB SD card as a print source This is what I had to do to get this working. There are two areas which need to be changed  CONFIG.INI on the TFT CONFIGURATION_ADV.H on the Marlin (2.X) build This solution is based around my configuration but is likely to be more generic, I think. I am running SKR 1.4 Turbo - Marlin 2.0.5.3 BTT TFT35 V3.0.26 Change Marlin Firmware You will need to create a new build, with the following changes in the configuration_adv.h file. First, you need to enable the onboard SD card as Then, to enable the long filenames change:  Remo
