Update: Bits and bobs

-

Today I have been doing various things to prepare for some work at the weekend. I'm hoping to install the upgraded LED bar, so I spent some time earlier in the day trying to get the diffuser to print in PETG.I got very close, but as it's only 0.4mm thick with a lot of bridging, it wasn't quite there. I shall probably try again just because it's a challenge. I think that if I push the extrusion multiplier up a notch, I may get there. I printed a new base successfully, but the diffuser is very thin indeed and it has only one extrusion width to hold to the bed too. 


In my defence, the photo shows the print after I deliberately overflexed it to see how much give it had.

It's now on my to-do list (under "printing challenges"). In the meantime, I can continue with the PLA version. 

In order to get to power to the new DC-DC converter, I need to splice the 24V rail. I thought that using some lever connectors would be nice, so I've been prototyping a mount for a pair of these. This actually turned out quite well for a first attempt, so I'm now creating a clamp bracket for it, to hold it in place on the extrusion and provide a cover. 

I can then splice the existing 24V rail between the PSU, the SKR mainboard and the new DC-DC converter. 

Inevitably I'm now printing the next batch of cable chains, albeit I'm only doing 20 now as a compromise. 


In other news, I had an exciting delivery today: two more SKR 1.4 Turbo mainboards and another set of five TMC2209 stepper drivers. AliExpress were having a sale so I decided that having spares, plus another which I plan to use to upgrade my Creator Pro with, after I've finished this project, would be worthwhile.

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
