Before I could get the official marlin-tantillus firmware to work, I used the repetier firmware with repetier host. But I got hooked on repetier host, and the firmware has some really nice features like eeprom saving of settings and binary communication. So I went back to the repetier firmware, but I had to do some modifications to get the fan working properly for example. The fork is on github here: [github.com] I don't have the LCD functions (eg. load/unload filament) implemented, because I don't have my LCD hooked up yet. But the fans are working correctly and printing from repetier host or sd card works great. Here's what I've done so far: - added description for Tantillus axis settings (see #TANTILLUS section in Cnfiguration.h) - combined extruder and main fan (on Tantillus same fan is used to cool carriage) - fan stays on to cool carriage while extruder reaches safe temperature after print finished - defined FAN_PIN for Azteeg X1 https://reprap.org/forum/read.php?279,217281,217281#msg-217281 Thu, 15 Oct 2026 15:54:09 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?279,217281,218599#msg-218599 https://reprap.org/forum/read.php?279,217281,218599#msg-218599 -------------------------------------------------------

Back when I used Teacup it was a little more like that. It had a separate config file for each board so to add a board you created a new config and added it to the repo. It is still under development and has recently had look-ahead added to it so it may be a viable option as well.]]> Sublime Tantillus Sat, 15 Jun 2013 17:51:08 -0400 https://reprap.org/forum/read.php?279,217281,218578#msg-218578 https://reprap.org/forum/read.php?279,217281,218578#msg-218578
I see your point about the firmware changing fast and with insufficient testing. Add to that all the #defines and #ifdef, with zero help for those from the arduino IDE, and you got insane craziness. I wish there was a firmware with some sort of plugin architecture instead off the wall of #defines.]]> lajos Tantillus Sat, 15 Jun 2013 15:55:16 -0400 https://reprap.org/forum/read.php?279,217281,218557#msg-218557 https://reprap.org/forum/read.php?279,217281,218557#msg-218557
One of the main reasons Tantillus has its own branch of Marlin is I had to do a bunch of work to the LCD code to get the relevant data to display on the 16x02 screen in the correct places. The main branch of Marlin at the time allowed you to set it to 16x02 but then had the numbers set in location to be at the far right side of a 20x04 screen. It also had a lot of the data on the extra two lines as well as not allowing you to scroll unless it had more than 4 lines of information and still only show two.

Also note that I am not a programmer so my code may not be that clean. Also my commits at the time are a mess and not labelled correctly.]]> Sublime Tantillus Sat, 15 Jun 2013 14:36:46 -0400 https://reprap.org/forum/read.php?279,217281,218538#msg-218538 https://reprap.org/forum/read.php?279,217281,218538#msg-218538
Probably neither route is small feat, but I was wondering if you think there are features in the latest marlin that would be nice to have.]]> lajos Tantillus Sat, 15 Jun 2013 12:50:34 -0400 https://reprap.org/forum/read.php?279,217281,218118#msg-218118 https://reprap.org/forum/read.php?279,217281,218118#msg-218118 Sublime Tantillus Thu, 13 Jun 2013 21:12:53 -0400 https://reprap.org/forum/read.php?279,217281,218111#msg-218111 https://reprap.org/forum/read.php?279,217281,218111#msg-218111 lajos Tantillus Thu, 13 Jun 2013 19:51:35 -0400 https://reprap.org/forum/read.php?279,217281,218074#msg-218074 https://reprap.org/forum/read.php?279,217281,218074#msg-218074
The SD transfer function has also been improved in Marlin since my branching that allows binary transfers which speed things up greatly.

Yes I use Ramps for all my Tantillus (Sanguinololu on my Prusa but no SD or screen)

Can you try the main branch of Marlin and see if the SD works for you there and then compare the pins.h to see if it is a pin issue?

The 4mm ID tubing works and there are a few machines using it (none I currently have). I think it is actually 5/32" ID]]> Sublime Tantillus Thu, 13 Jun 2013 16:57:36 -0400 https://reprap.org/forum/read.php?279,217281,218068#msg-218068 https://reprap.org/forum/read.php?279,217281,218068#msg-218068
You use ramps, right? Wonder if it could be a sanguino incompatibility.

I'm pretty sure marlin supports the i2c driver chip I got, once I have the board built, I will test it with marlin-tantillus.

And off topic, I'll have to look into 4mm ID bowden mod, I have two spools of gorgeous red pla that the 1/8" ID bowden is too tight for. I saw some posts of yours where you mentioned you also use 4mm bowden on some of your machines.]]> lajos Tantillus Thu, 13 Jun 2013 16:39:48 -0400 https://reprap.org/forum/read.php?279,217281,218027#msg-218027 https://reprap.org/forum/read.php?279,217281,218027#msg-218027
I am not sure how the I2C screen will work with Tantillus' branch of Marlin as it may not currently have support for it. If it has been added to the main branch of Marlin I may just be able to pull the commits but it may also be in a part that has changed drastically and not be merge-able any longer. Then it would require a re-write of either the I2C part or all of my changes into the current Marlin.]]> Sublime Tantillus Thu, 13 Jun 2013 13:40:09 -0400 https://reprap.org/forum/read.php?279,217281,218017#msg-218017 https://reprap.org/forum/read.php?279,217281,218017#msg-218017
One issue I'm having with marlin is with the sdcard. When I transfer files to the card on my pc, stick it in sdramps, they don't show up in marlin. The card is formatted FAT and the file names are 8.3. But with repertier there's no issues, even can see long filenames (although truncated to 8.3). Have you experienced any sdcard troubles with marlin? Do you use pronterface to transfer the files, or do you use an sdcard reader?

My i2c driver chip arrived, I'll make a pcb for it and then hopefully I'll have lcd on my tantillus soon!]]> lajos Tantillus Thu, 13 Jun 2013 12:18:37 -0400 https://reprap.org/forum/read.php?279,217281,217887#msg-217887 https://reprap.org/forum/read.php?279,217281,217887#msg-217887
For the eeprom I just have it disabled in the Tantillus branch of Marlin as it can lead to troubleshooting issues when someone changes a setting on the LCD and saves it. Then they update the firmware and the new settings do not work because the eeprom saved ones overwrite the defaults in the firmware. If anyone wants them just uncomment the eeprom line in the config.]]> Sublime Tantillus Thu, 13 Jun 2013 03:10:35 -0400 https://reprap.org/forum/read.php?279,217281,217281#msg-217281 https://reprap.org/forum/read.php?279,217281,217281#msg-217281
