Behind the scenes

-
You may be wondering how the new devices have been connected without a new mainboard as that stage isn't yet published. Well, the BTT SKR1.4 Pro has long since replaced the standard A8 Plus mainboard. However, it is still sitting on the table with cables hanging out of it as I test things.

It may not be pretty, but...

It is fitted into the case I have designed, has the EEPROM and DC-DC modules installed and is working. However, I intend to create a full cable harness for the project and can't really do that until the ancillary parts are in situ and working. I can then create a mount for the case. The case itself has a flange mounting system which will allow me to mount it in many orientations by having different brackets.

I haven't yet published this side of things as, simply, I am waiting to complete it and as it is the heart of the system, it has to be fully correct. 

Another element which has been running for some time are the custom endstop mounts. These were one of the first things I designed as they were critical to having the printer working. These allow smoothed endstops to be mounted to the chassis, allowing for adjustment of each. I have one for each of X, Y and Z axes. The Z axis one is no longer being used since the installation of the BL-Touch, but I've left it in place.

I hope to release these elements, at least, very soon as they're working well and have been for some time.

      Thanks. I have now (I think) finally decided on how best to get the cabling to the carriage and am working on Z and X cable chains. It was that or a cable suspended from the gantry, but I think that cable chains (though a lot more work) is the more elegant solution.

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
