TEMPLOT 3D PLUG TRACK - To get up to speed with this experimental project click here.
@Steve_CornfordI again had trouble with the L1 chair, got through 5 before managing to get the loose jaw fitted.
Now that folks are beginning to use plug track for real, an obvious frustration must be not having most of the settings changes preserved between sessions. The current save custom buttons don't save much more than the rail section data. I think it would be better if the plug track settings were included in the existing program preferences mechanism, so that they can be loaded automatically if desired, and several different preferences files can be created.
@Paul BoydHi Martin,
This is all getting quite exciting, although there is still no way I can have a resin printer!
Just a thought on this:-
Would it be better to keep program preferences separate from plug track preferences? I'm thinking of the situation where people use different rail sections so would want to save those preferences, but then not have to remember to update any program preferences if a change is made but to a different preference file.
A sort of analogy is that you don't keep printer calibration settings as part of the main program preferences but as separate files.
I'm thinking that Templot would open with the normal saved program preferences, then if a user wanted to use plug track or even just timber bricks then a separate settings file would be loaded - again in the same way we load any one of a number of printer/paper settings. I envisage lots of plug track/timber brick settings files to choose from!
I may have misunderstood your intention entirely, of course!
@Steve_CornfordJust washing a new batch of chairs.
Plunge bath , tick
First wash, tick
First blow through, WIP

I have printed one L1 raft across the build plate, and one along.
I will try fit of jaw whilst chair still on raft, and then once inserted.
Repeat for both orientations.
Yes I used a Scalefour metal folding jig, although to be honest the jig is not perfect as it does not support the whole depth of the rail.
The slot could be deeper, and then a recess where the clamping bolt goes through so that the effective depth of the slot where the rail is clamped is the same as now. I expect your design is better.
@Steve_CornfordThat looks really good Martin.
Would there be any chance of adding another rail groove in each half that ran parallel to the longest side about half way down the shortest side please?
@Terry DownesMartin, do You think You will be programming the slab and bracket chairs before the remaining crossing chairs e.g. L1CC, DN, DA, DB
Yes it is in the current release.
I am just trying to understand all the options.
I tried printing some L1 jaws with the three loose jaw pin clearance parameters that you highlighted increased from the default by 0.01, but I think this makes the pins too weak, so perhaps I will try again but this time only increase the "front-inner" by 0.01, making it a clearance 0.02mm
Perhaps i will also generate a raft with the slot size increased from 0.6 to 0.62.
But first I have to cook supper!
A resin print would be much better as a soldering jig. On the other hand the resin is not remotely resistant to being filed.
@JFSOops, a generalisation too far I fear!
True for some resins, but if you need a tough print, use a tough resin - I used Siraya Tech Build for a recent job because it is very abrasion resistant, has high yield, low modulus and it takes detail very well. Which would make it too brittle for chairs, but perfect for a filing jig! There are many, many different resins available and it makes sense to me to only use those which publish mechanical properties and to select carefully according to the final purpose. To complicate matters, most of the (eg) Siraya Tech resins can be mixed to achieve intermerdiate properties. Unfortunately, the very best resins are not cheap, but then we need adequate, not best!
I have noticed people say that the prints they have made are "weak" and wonder what led them to their particular choice of resin for the job? Personally, for chairs (which I have yet to have a go at !!), I might be tempted to invest in a bottle of Siraya Tech Tough for a first go as it has a high elasticity, and blend it 50:50 with the Build to avoid too much plastic deformation in the resultant prints.
No good for a filing jig though ...
Watching with interest!
@Steve_CornfordBut for now I hope you are having fun with the Filing Jigs!
