Quotetomas02 Where did you source the t slot from and approximately how much was it? Tough stuff to find in NZ From China, like most of the stuff I use :by jimjimma - New Zealand RepRap User Group
Thanks Zerker. Yes, the new bot will have a fully enclosed dibond chamber. Ingentis does too, I just have the panels off at present while I'm tinkering .by jimjimma - New Zealand RepRap User Group
Hi Folks I've intermittently posted in this group in the past but I don't think I'd ever really got around to introducing myself or my projects properly. So, I've been working on a large T-Slot Tantillus variant christened 'Ingentis' (by Sublime) for quite a while now, its been working for quite some time and the design is constantly evolving but I thought you might like to see what's been happeby jimjimma - New Zealand RepRap User Group
Hi Folks I was fortunate enough to receive a 'review' roll of Taulman 'Bridge' nylon copolymer and as such, I've done a video review. It's rather longer than I hoped for (13mins) but I hope it's useful to those with an interest in the product. I'm happy to answer any questions arising etc. If you want to cut to the chase. Start from about 9mins in. Taulman Bridge Video Reviewby jimjimma - General
Sorry I've been absent and not very responsive recently. Just started new job and wifey was finishing PhD. Plus I've been printing prosthetic fingers for a guy in the US. Anyway, enough excuses. Sublime, I really like the water wheel damper idea . I'm also getting back onto the multimateral script as I'm keen to see what happens with combining Taulman bridge an tglase. Will post once I'vby jimjimma - Tantillus
Hey Dale No, I've been slack and keep changing things and have limited spare time and I'm over committed wrt to half finished projects and I'm slack. Would the currecnt version as a complete STEP help in the short term.by jimjimma - Tantillus
Hiya Sublime, Just wanted to let you know that I've not lost interest in this. Just have had very little spare time and on top of that, I've found the airtripper cold end I'm using isn't performing well with Tglase and as a result I've embarked on finalising the design for 2:1 ratio belt driven extruder which uses a MK7 hobbed pulley rather than a hobbed bolt. As soon as I've got dual extrusionby jimjimma - Tantillus
Hmm, Sorry it's been a few days - life interfering with printers. There is still something up with the new code.You'll see in the gcode snippet below, it seems to be putting in G92 commands with a negative E value even though it's using relative E. It's also retracting but not priming as far as I can see. The end result is the T1 filament gradually backing out of the extruder. I had a quick loby jimjimma - Tantillus
QuoteSublime Ok the G92 E0 issue should now be fixed and the prime pillar is forced on layers without a tool change. re-link alright, further progress this evening. Prime pillar works well for E0 although I found I needed to add a layer of blue tape in the prime pillar location to get the first layer to adhere, in an ideal world I think the first layer of the prime pillar should be a solid inby jimjimma - Tantillus
QuoteRobonz Forgive me if I have not read the post very well. The professional machines have a brush and silicone squeegee. Every time they do head change they drive the head over to the brush and wiper and give it a few wipes, then extruder a few cm of plastic then wipe again, then back to printing. It works really well. If my printer was not limited to 100mm I would have added one already for pby jimjimma - Tantillus
Alright, so I've gone to bed as it's been a hard week and my brain wasn't functioning very well. The extra G92 E0 didn't have effect but only because I forgot to include a carriage return at the end of the line. Learnings from this evening: For tgalse, it's pretty much mandatory to have a prime tower or prime area or something because it oozes like crazy even when you drop it to 200 degrees anby jimjimma - Tantillus

Have you scaled up the Tantillus for your large machine or is it something completely different? For the multimaterial 'bonding' layer changes. It had occurred to me that you could do an initial parse that performs an N+1 find and replace of the 'sparce' comment with 'solid' in the gcode for a configurable number of layers before doing any of the tool change processing. Hmm, in fact you could reby jimjimma - Tantillus
That is great - I will get to try it out tonight. Can you PM me your email address? or Just email me directly, my address is somewhere on page5 of this thread. The E3d guys would like to show their appreciation for the work you've done on this as it's really going to help Kraken users until this sort of capability is integrated into slicers. Thanks again, I know I keep saying thanks but I'm blowby jimjimma - Tantillus
QuoteSublime OK it was travelling to the TCL because the Idle temp was set to 210. For the not enough priming at least on the first tool change it may be a result of the fact that your retraction length is greater then the Absolute E value so far at that point so it puts E into the negative which means if the software endstops are enabled it may be ignoring the -E and reducing the prime by thatby jimjimma - Tantillus
Here is the original unprocessed file and here is the processed one. I have had no time to look at it so far so it may be something blindingly obvious.by jimjimma - Tantillus
GAh - whole evening wasted sorting out some thermistor problems. WIll be another 24 before I can do some more tests. I noticed I had wipe enabled - that may have been causing issues. I'll post some sample GCode shortly.by jimjimma - Tantillus
Progress! It's changing tools and not moving to TCL that often. Current issue is it's not repriming T0 (perims) enough once it starts using T1 for sparse so the perimeters aren't being created. I'll do some more testing shortly. It also does some very slow moves to loop start position just after tool change from T1 to T0.by jimjimma - Tantillus
QuoteSublime Yes it should be easy to add an if the tool has not changed statement to insure it does not change the tool over and over again to the current tool. Cool. QuoteSublime I can also make the M109 configurable. But if you have it cooling the unused hotend and try to print before it is up to temp it could be an issue. The idle temps are generally only what, 10 lower than extrusion tempsby jimjimma - Tantillus
I've sliced a model with new script and got it running remotely while I'm at work and what I could see on the webcam wasn't promising For loops, perimeters and solid infill, where I'm using the same tool. It still go's off to TCL after every loop and waits to hit target temp - it then moves back to the part very slowly - I assume this is because it's the Feedrate associated the next G1 commandby jimjimma - Tantillus
Hmmm Ok, so i've got the script running and it changes the tool for infill but it also iteratively offsets each layer by a certain value in the X and Y axis relative to the previous layer - I thought it was the nozzle offset intitially but it's slight larger distance. if you stick a bit of processed gcode in repetier or whatever the problem is pretty obvious. I had a bit of a look at the code buby jimjimma - Tantillus
QuoteSublime My wife was home today so I had time to add the features. It now has settings for each extruders retraction, filament diameters and gain. Let me know if it works for you. Awesome, mine is in the final stages of a PHD so I'm not getting much spare time at present. I'll have go with the script this evening though. Incidentally, if you were inclined, the relevant code in Cura that defby jimjimma - Tantillus
QuoteSublime I realize now I need to add retraction as well as flow rate adjustment since the hobbed bolts will not be the exact same as well as the firmware not having independent steps per mm. Should I add separate retraction settings for each extruder or one global one? Should it compensate for filament diameter differences as well as hobbed bolt differences? Maybe slice everything with a fby jimjimma - Tantillus
@Sublime Oh, awesome. That is perfect. I had already started thinking about this as I knew Kiss had such good annotations in it's gcode. I really hate slic3r so it's a good way forward, my only qualm is the apparent lack of developent with Kiss now, last time I looked, the forum was a spam-fest and it appeared that Jonothan had fallen off the map....

Quotekarabas Will you place extruders above the box to make bowdens shorter? like this Not sure. At some stage I'll go for enclosing the bot and that will mean accommodating for the Bowden tubes etc with an extra void space at the top of the machine, it may be possible to place the extruders at the top of this space but I really don't want some ugly apparatus mounted above the bot as shown inby jimjimma - Tantillus
QuoteSublime Is there any way for anyone to contact you that does not involve handing over all your personal information to big brother (Google +). I for one have stopped using most of Googles services (other than search) because of them trying to force people to use their social networking service.

QuoteFinch Hello All. I have decided to build this printer. I started to print parts. I noticed that "Shaft Bearing Mounts" have apertures on the both sides. One is for inserting the bearing, I cant figure out why the bigger on the apposite side is for? On the pictures of the printer there is also only one aperture for bearing. So am a bit confused. Thanks for answers. Hi Finch, the large holeby jimjimma - Tantillus
Thanks for that very detailed resposne Sublime - I have been playing around with settings and in some cases your values work and in others they cause some prolems, not entirely suprising given the variations from the Tantillus design. I am crazy busy at present but I'll get an update out on the Ingentis over the next week - it is pretty much done now, baring a few minor modifications. Also, I'veby jimjimma - Tantillus
I've got a half baked idea for a twin hobbed solution as Sublime describes if your interested. Also, I clean my hot end with nylon: push it through at 230 drop the temp to 190 and pull it out. Amazing how much burnt ABS comes out. 5-10 cycles is all it takes. Credit to Whosa whatsis for this method.by jimjimma - Tantillus
Here is another test print - something of a mixed bag as the overhangs on this model are well past 45 degrees and with ABS (no cooling) the surface finish really suffers. The surface finish on the rest of it is awesome though, the photos don't do it justice really but you can barely discern the layers either visually or by touch. Clearly, the Z belt drive seems to be reliable. Printed at 0.1mm wiby jimjimma - Tantillus
