Having such difficult time in calibration stage...

[danmoozing]

Hi guys~

I'm having such a hard time for calibration. According to instruction, at the beginning, I have to type "[G28]

If I type [G28], all axis would move up till endstop.
It's good until here....
Problem is, it will never stop at the endstop. I checked whether endstop works by typing [M119]. everything works but.....lol
I have used almost 3 days to figure this out but I couldn't find the reason.

Also There is more problem which are switches on Repetier-Host V0.83.

1. Onyx Hotbed doesn't work(I've checked wire many times but....)
2. When I move stepper motor, Stop Motor switch never stop motors. (SO I had to disconnect and connect again. then it stop moving)
3. When I click Z Arrow on Repetier, not like x or y axis, it moves veeeeeery slowly with strange sounds.
( but if I type g1 z50 something like this, it moves normal speed)
3-1 If I click axis arrows many times, it never stops moving. (Then I have to disconnect and connect again lol)
4. Heat Extruder works well
5. How to calibrate home? where is home?
6. What is meaning of "For this step you WILL need to have downloaded the Arduino IDE and the Rostock MAX firmware source code." in the instruction?
(as a newbie, it's really difficult to figure out)

I'm making Rostock Max for a week. Please let me enjoy 3d printing like you guys.

Thanks a lot in advance ^^

Lot's going on there! Let's start with the basics:

What firmware are you using and where and when did you get it? Let's get endstops and movement and other mechanical/electrical issues working before jumping to calibration.

It sounds like maybe you have a configuration issue if the end stop wiring is correct but not working.

Do you see a temperature reading for your heated bed even though it doesn't heat up? It should read room temperature.

Your #6 - this tells me you probably don't have a workable firmware release and need to get this set up first! The firmware is compiled and downloaded to the RAMBo (are you using RAMBo?) using the Arduino IDE. So, first go grab and install Arduino 1.0.3. Then grab the firmware source from Polygonhell - there are links on my build thread and all over this forum!

Then, report back and we'll help you get connected and installing the firmware!

[danmoozing]

Thanks for replying ^^

I'll tell you what I've done so far.

1. firmwares I have
+ arduino 1.0.3-windows
+ Gen7+Arduino+IDE+Support+2.1
+ Marlin-for-rostockmax-rambo-master
+ Repetier-firmware-master

but I don't know how to do with Gen7 and Marlin with arduino. I just put that folder in arduino IDE-Hardware folder. If I compile Marlin.PDE it works but I don't know what I do more. I don't understand why instruction doesn't contain this process.

2. Repetier v0.83 --> this morning updated v0.84

a. When I click Z-Axis-Arrow, it moves really weird. veeery slow and makes strange sound like something wrong. I do not want to click that anymore lol.
b. endstop works. I've checked by [m119] and all of endstop marked "h" which means it is recognized, isn't it?
c. Even though "b" when I do [G28], it doesn't stop until endstop. so I have to power down. Sometimes it stops one axis and another axis stop, after then, last axis didn't stop. Which means it's not wiring problem.
d. [g1 z50 f1200] this code should take head 50 above hotbed. But I understood that I have to do [G28] in advance because I have to make hotbed as "home". But I can do after [G28] because of "c" reason. therefore, if I do [gi z50 f1200], head moves but stop in the middle of the machine.

3. I cannot do more process because of those reason. Please help me..... I bought Rostock max but I've never been used yet lol.

Ok, let's start with a known fgood firmware. Please download the firmware from here: https://github.com/polygonhell/Repetier ... evelopment

This is Polygonhell's preconfigured Repetier firmware. Once you have downloaded it, open it in the Arduino IDE and upload it to your RAMBo board. Then test the G28 and tell us what happens.

Please do this exactly so we can eliminate other variables.

Thanks,
Michael

After you're done uploading are there any error messages at the bottom of the arduino IDE window? It should say "Done Uploading" in the status bar at the bottom. If not make sure you've hit "upload" not "verify" and that you have the right board and serial port selected.

[danmoozing]

OK, I've done everything you guys adviced. However.... still doesn't stop when it touches endstop...
Uploaded Marlin or Repetier both of them one by one. what is my problem...

and if I run [M119] pushing endstops, it will show

x_max:H y_max:H z_max:H

what can I do......

[mhackney]

Ok, make sure the Repetier firmware I linked to above is installed. Please stop trying different firmwares until we get to the bottom of this! It will only frustrate you and us!

Once you have the firmware installed, DO NOT connect to the printer. Before connecting, manually move the X, Y and Z carriages (slowly so you do not create a big back surge) to within 10 cm of the stops at the top. Now, connect to the printer.

Issue the M119 and report what you see:

Manually (DO NOT USE THE host, simply grab it with your hand and move it) move the X carriage up until it clicks the switch. Issue the M119 and report what you see now:

Manually move the Y carriage up until it clicks the switch. Issue the M119 and report what you see now:

Manually move the Z carriage up until it clicks the switch. Issue the M119 and report what you see now:

Now, move the X carriage down so it is 10 cm below the switch. The Y and Z should be pressing the switches. Click the Home All button and report what happens:

Click the Stop Motor button and reposition all 3 carriages so they are depressing the switches. Now, move the Y carriage down so it is 10 cm below the switch. The Y and Z should be pressing the switches. Click the Home All button and report what happens:

Repeat this with the Z axis and report what happens:

Once you've done this EXACTLY as requested, report back here and we'll take it from there.

Mhackney,
Not sure if I should make a new thread for this but what exactly do I open in the Arduino IDE to be able to use polygonhell's firmware? Do I just download the whole file and the open the file marked Repetier pde and the upload that to the Rambo?

I am not sure I am doing this right. I used the link to github you posted but sort of lost after that.

[mhackney]

That's correct. Once you open it, click the upload button. That will compile the files and the upload the firmware binary to the RAMBo. Then you should be good to go.

[rs50pilot]

Thank you,
I was looking for a file that had his name attached to it or something. I thought that file was the samething that is on the rambo as it came from seeme. Thanks. I just got the machine up and running today and I need to figure out how to change the steps as I have the 1.1 rambo and it must be set to 8 and not 16. Thanks again. I want to get this thing calibrated and printing.

[mhackney]

Go read my build thread, I tell what you need to modify for 16 micro steps.

[cadfab3d]

ok start with the simple things in repiteir check you printer config file make sure you endstops are set to x,0 y,0 z,max when you run the m119 it aont show any thing different. i also mad the same mistake and had an issue. also when going to the endo stops run the m 119 again and MAKE sure when you press the x axis end stop the x axis endstop is showing h etc because if you have your micro switches mix up on the board it WILL DO THE EXACT SAME THING. just remember there is no such thing as a smart person just someone who has already @!#% something up before you lol good luck.
