Update: new BL-Touch mount with nozzle LED

-

Today I have been working on installing the final cables into the chains. Having everything demountable was a lot more work, but it will make later changes and upgrades far simpler. 

I started by creating the LED mount itself


This takes a single Neopixel LED and connects a 5V power feed and data in and out. The 5V is already on the carriage and so, now, is the Neopixel data.

This mounts to the modified BL-Touch mount as

The other side of the mount now has low-profile cable routing included for both the new LED and the BL-Touch cabling

The modified mount uses the same fixings as the original - to the rear of the carriage.

I then needed to modify Marlin to increase the number of LEDs from 46 to 47. The other change is to add the facility to have a static Neopixel LED


The cabling in the chain is now complete and it needs to be re-attached to the newly modified carriage mount. I have also been adding clear labelling to each of the cables so that they make sense in a few months' time.


One other thing I have created is a modifed chain link for the carriage end as this bears most of the load. I have simply increased the length of the linking pillar to stop it being able to rotate. This simple change seems to have strengthened it significantly. The others in the chain seem not to need this. 
 
Now comes the task of reconnecting the parts and securing the cabling to the new integrated bases.

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
