Issues with getting printer with Smoothieboard running

Hi folks,
My name is Michael and i am an electrical engineer. I am with hobby 3d printing for now 3 years, until now only with small sized printers like ender 3 and CR10S which cant really give me the reliability and possibilitys which i would like to have. Especially because i want to use my printer for mechanical functional parts, means they have to be precise and solid to achieve the mechanical properties i was planning before.

So i started to building currently a 3d printer with the size of 400x400x600mm build area.
I choose the smoothieboard v1.3 to get all this running quite fast and reliable. So i also choose to use NEMA 23 size stepper motors with integrated drives with 3nm of torque from JMC to make it easier in case something is broken.

Unfortunly i have a problem to get this steppers connected to the smoothieboard.
The connection is like that, i adjusted the pins as open drain and connected all like it should work.
Because it didnt work, i watched with my oscilloscope to the pins and no signal appeared. Maybe i doing something wrong by using the move comands on the touchscreen or something else?

I didnt work before this project with the smoothieboard so could you please help me with this?

I have moved this to the Smoothie category so that you will get a better response. :slight_smile:

Hi,
thank you very much, sorry i didnt see that there is a smoothieboard category.

Hi guys,
what i realized now is that my board isnt using the config file. because it is still written as .txt and not .CUR

Seems there is a issue. Also my TFT isnt working seems to be.

The firmware.bin file is the one that gets renamed to firmware.cur The config file is always named config.txt Can you post some pictures of your wiring?

As far as i know there is not smoothieboard v1.3, only 1.0 & 1.1… perhaps you mean MKS SBASE V1.3 ?

Hi,
Yes i can send you later pictures. About the board, you are right, it is the mks sbase v1. 3 together with the tft32.

Greetings Michael

Hi guys,
now with pictures for you and technical details:

I attached you my config file, that you can see what i did, maybe there are some mistakes.

It is attached 2 Extruder motors at E0 and E1, to this 2 heatings for E0 and E1 and a thermistor aswell for E0 and E1. E1 has tourque and E0 not, but there i think it is a wiring problem. But it still didnt move.

Like you see, i have no reading of the thermistors, and the room has 20 degree celsius. I have there a other temperature measurment device. The XYZ motors are directly attached to the pins for the signals, all signals are used, and these are configured as open drain. On the + side of the signal there is +5V and on the mainboard i switch to ground. But there is no signal avialable.

Greetings Michael

Well, it’s not unusual for it not to move if it’s wired wrong. Have you checked the poles on your stepper with an ohmmeter?

Currently not but i will.
So first of all i have to wire correctly?

Hi,
Just a general question, should i connect first all wires before i start? I mean also the switches and so on?

Just making sure here, you do understand how a bipolar stepper motor works, right? If you haven’t identified the coils correctly, it won’t move and won’t even hold still since you won’t have a circuit…

Or are you saying you put a scope on the step and direction signals and you aren’t seeing activity on E0 step/dir?

I’m not a smoothie expert, just trying to get the obvious questions clearly answered for those who do know smoothie so they can help.

Hi,
Yes i know how a stepper works. I was first on the coil lines, then i didnt see any signal, so i was measuring on the pulse and direction pins and also didnt see anything.
That was on X axis.

Greetings

Edit: The other lines show the same behavior.

Hi,
I just had a idea, i have a second board here, and also small steppers which are usally used. I will put everything together and test it seperate and then put it on the printer. Maybe that gives me the possibility to understand what i did wrong.

Hi Michael,

I am also working on my first DIY 3d Printer.
I also got issues with the stepper motor. Nothing worked at the beginning.
Did you test the motors through the TFT user interface or via USB?
My problem is that - after sorting out some issues with the jumper setting of the stepper driver board (I am using a board with addon stepper drivers) the motors only move, when connect the USB to a PC and run them through Pronterface (G-commands).
I still cannot get any movement when using the touch screen (“Home” or “Move” menu).

In addition check if your homing switch is connected properly. In my case the system was set to the secure way using a switch with NC and C while my switch assembly was supplying a NO signal. After suing a standalone switch with NC and pullup at the signal input homing was workin perfectly and safe (opening switches are kind of standard in industrial applications).

Best regards
Onki

Makes sense.

If I read you right, you are experiencing holding torque on one extruder but not the other. Looking at your configuration you have the entire second extruder configuration commented out. So it would make sense for it not to be enabled.

Checking pin mappings:

A quick web search says those are the right pin mappings.

With those commented out I don’t think your second extruder is going to do much! :slight_smile: Then obviously you need the correct pin mappings. I have no idea what they would be on MKS v1.3

Do note that @Arthur_Wolf has warned about the MKS v1.3 boards being too slow:

MKS uses a 100Mhz chip instead of the 120Mhz chip that Smoothieware is written for ( and that is on the Smoothieboard ). This means as time goes by, it’s going to be less and less likely for Smoothie firmware to run on MKS. We are already seeing more and more problems as time passes, and we expect as we implement the next set of major features, you won’t be able to use the MKS board at all.

Looks like @onki69 has more useful information for you about trying through USB rather than screen.

Hi, thanks, that makes sense at all.
Yes it is commented out, i didnt see that at all. And with the end switches makes also sense.

About the mks v1. 3 is to slow i didnt know. Ok thats bad but not a show stopper for now i think. Anyway i will test it and make the changes this evening and then when all is running i will put the settings to my printer.
I write you in the evening back when i have something new.
Thank you very much guys.

I really should stop to work after 12 oclock

Hi guys, i just have a other question, i case that this will not work like it shoud be, which smoothieboard i shoud chose for 2 extruders and this printer? The target is to achive 1m/s printing speed in infill.

Thanks for your help guys

Hi guys,
was so successfull. I attached on the new out of the box board 5 nema 17 steppers, directly, i also connected with 3 wires directly the switch pins, so it has the signals. Unfortunly the display didnt also work, and also the USB connection with pronterface didnt work.

I uncommented the lines you told me.

Greetings

Just to be clear, I don’t have any reason why it’s only uncommenting those lines. You need to check the pin assignments, which might include asking MKS, and probably more of the extruder configuration.

(Again, I don’t personally have smoothie, I’m just reasoning here.)
