first connecting to mac Hi, my tantillus is finished and I've connected electronics to start settings! I use repetier-host , I connect it but I have an error concerning j-head temperature! I don't see it, inticates zero degrees! termocouple is connected on T0 and D10 for temperature cables I connect endstop and only x motor can someone help me? what settings needed in marlin?

I solved this problem!
I recalculated the steps per mm using this [calculator.josefprusa.cz]
Now the printer is fine, just settle the whole thing and when I'll make some decent print I'll public some photos!
with respect to the z axis, I used to twice the silicone tube and the holder printable but it happened that was cut and had to do it again.
can you better explain problems regarding use of the coupler?
why it creates problems?
For the moment I'm using Cura but as soon as possible I would like to resolve the problems with kisslicer

The main issue with those Z couplers comes from the holes being slightly over size which means the shafts are not perfectly centered. The next issue comes from the fact that we are supporting the weight of the Z axis and those couplers are not designed to do so. This can be overcome by making sure the threaded rod touches the top of the motor shaft so the weight gets transferred through to the motor bearings. Also if the shafts are not touching each other the coupler can act like a spring vertically which could result in non-linear movements.]]> Sublime Tantillus Wed, 06 Aug 2014 11:30:34 -0400 https://reprap.org/forum/read.php?279,376183,391437#msg-391437 Re: first connecting to mac https://reprap.org/forum/read.php?279,376183,391437#msg-391437 I recalculated the steps per mm using this [calculator.josefprusa.cz]

I'm using pronterface and kisslicer but I could not!
I set all the different settings but when I start a print of a gcode generated by kisslicer, the printer seems crazy!
especially the extruder runs faster without stopping!

Sounds like you switched kisslicer from Relative E to Absolute E without changing the firmware to match (Cura uses Absolute E but inserts the command to temporarily change the firmware to Absolute). This why you should not change anything from the default config unless you are completely sure of what you are doing.

I did three prints of which I enclose photos by using Cura and start the printer with repetier-host
The main problem is z-axis, for example the cube 20x20x10 has been realized only half empty and the cube 2x2x1 the same!
also measures of the latter along the x and y are not real, in fact, measure 3x0.5 cm!
calibration angle 50mm is 75mm!!
the third printed file (the one that came better), is a cm bigger( calibration angle 50mm is 75mm!!)
I have a z-axis threaded rod 6cm connected with coupler

This all sounds like a problem with your steps per mm because of your belts and pulleys instead of the cables. Also possibly you are using a metric threaded rod and not the original imperial one which would result in the Z being wrong too. You need to know how to set all of these if you are going to be changing things from the original design.

Also note that those couplers are a known source of Z axis problems and the printed one should be used.]]> Sublime Tantillus Sat, 02 Aug 2014 17:22:40 -0400 https://reprap.org/forum/read.php?279,376183,390310#msg-390310 Re: first connecting to mac https://reprap.org/forum/read.php?279,376183,390310#msg-390310 I put new printed lm8uu and works smooth!

Get your printed bearings running smooth and it should be fine. Those are good motors.

If you have motors like that then the acceleration should be turned down to match the slow response and possibly the max feed rate too. M201 command would sort the acceleration? or tune the firware.

My comment was about his motors being rated at 12v @ 1.7A and having 30ohm coils which means the time it takes to reach the full 1.7A may be longer than the step takes. This would result in less current going to the motor which equals less torque. Most RepRaps run motors rated at 2.8v @ 1.65A motors which have 1.65ohm coils and can reach full current very quickly.]]> Sublime Tantillus Thu, 31 Jul 2014 20:57:42 -0400 https://reprap.org/forum/read.php?279,376183,389824#msg-389824 Re: first connecting to mac https://reprap.org/forum/read.php?279,376183,389824#msg-389824
The motor controllers are constant current so stall torque should be about the same at 12 volts and15 volts. It is the top speed and acceleration that suffer with lower voltage (or torque at speed) Our X,Y dont get into that area where they suffer but the extruder does.

Obviously to run on 12 volts the machine needs to run very smoothly with low friction. I was surprised I can get away with 12 volts. I also changed my extruder motor to a 0.9 degree motor, as it runs so slow. The 1.8 degree did work ok though.

The other thing that could be an issue are the motors. If you are still running the 12v motors you will not be able to put much current through them do to there resistance being as high as it is. Without being able to run them at a high current you may not have enough torque. The next thing I would check are all the grub screws to see if they are tight since they can cause layer shifts if the grub screws are loose on the gears and in your case on the pulleys for the belts.]]> Sublime Tantillus Thu, 31 Jul 2014 12:24:21 -0400 https://reprap.org/forum/read.php?279,376183,389560#msg-389560 Re: first connecting to mac https://reprap.org/forum/read.php?279,376183,389560#msg-389560
Here are my KissSlicer settings,

www.edns.co.nz/tantillus/kissslicer_settings/

Beware I have a lot of prefix code in the Ptr G-Code section and some postfix too. Some specific to my machine. Most of it is nicely documented so you can understand why I did it. The settings are all optimised for my 0.4mm jhead and local plastic and heated bed.

You should use Sublimes settings found here "Configuration files' here to get started, then read through some of my gcode for customisation. e.g. PID temperature control and a start up routine.

maybe part of the problem may also be what you say (waiting for a response to Sublime)
but the problem is another and at this point my question is:

pronterface and kisslicer are two separate things in the sense that, whereas the manual controls work well, just a well-gcode generated and the pinter should be a good start!
so if anyone of you who has a tantillus pass a gcode generated certainly well (ie with the parameters set in the right way), my printer should work!]]> mdcompositi Tantillus Thu, 31 Jul 2014 05:00:16 -0400 https://reprap.org/forum/read.php?279,376183,389457#msg-389457 Re: first connecting to mac https://reprap.org/forum/read.php?279,376183,389457#msg-389457
If you hand turn the x or y motors, the effort required should be very smooth and easy. If this is not true then some work needs to be done until it is.

Good luck

In Kisslicer make sure the bed center is set as 50 50

When you first plug in the machine make sure the carriage is in the back right corner (also that the motors move away from the back right corner when you move them in the positive direction). After plugging in the machine with the carriage in the back right corner do not move it with your hands.]]> Sublime Tantillus Thu, 24 Jul 2014 11:56:31 -0400 https://reprap.org/forum/read.php?279,376183,387057#msg-387057 Re: first connecting to mac https://reprap.org/forum/read.php?279,376183,387057#msg-387057
