H2 Hacker Z axis not moving...

Post by Fe_Lantern »

Recently was very fortunate and won a H2 Delta Hacker kit. While I do own two Robo3d R1+ machines, this is my first 3d printer kit. I have it all built and the Repetier firmware loaded into the mini-RAMBo to the best of my ability. While everything else appears to be working I have found that my Z-axis will not move by itself. When I tried to calibrate the printer Both the X and Y will move and attempt to drag the Z axis.

Looking for possible solutions, I did find out to check if the Z-axis stepper was a dud or not, I have swapped the Z-axis with another axis on the mini-RAMBo board and it functioned normally, while the other axis did not. So it is either a board issue or a firmware issue. I am attempting to find a fault/error it the firmware, but this is all fresh to me and I am not certain what to look for. Most troubleshooting threads I have seen were dealing with a inverted, but still moving Z-axis, or were on different machines.

Use the gcode console to pass it an M119. An open on the endstop will cause that axis to think the endstop is triggered and it may not move or move only subtly. Just to rule out that possibility...

Ran it through and it seems to be acting the same

Just a note of printer behavior:
When homing- the X-axis will raise and hit the endstop repeatedly for a couple of seconds, pause, and repeat once. This happens with the Y-axis just an inch or so short of the endstop and the Z-axis is as low as the other two will allow.

M119 doesn't change anything. It just prints the endstop states to the console. I don't use it often enough to remember the convention, but the states are High or Low and they should all be the same when the endstops are not triggered and reverse when the corresponding endstop is triggered.

Fe_Lantern, that behavior you described sounds like the end stop switches are not plugged into the right axis connectors on the Mini-Rambo.

Pull the carriages away from the top so none of the switches can be hit. Enter M119 at the console. All three should show "L" as their state. If one or more does not, you've either got a short in the wire (unlikely), or you've wired the switch incorrectly (possible).

If all three show "L", then test each switch by holding the switch closed with the end stop screw on the carriage and enter M119 again. The axis that is being activated should show "H". If the axis that shows activation isn't the one being activated, then the end stop switch is plugged into the wrong location on the controller. Do this test for each axis.

It looks like I somehow managed to switch the X and Y on the board. After putting them in the correct locations, the M119 manual switch test showed everything was okay. It can successfully home, and I have done the initial calibration/level with no troubles. Following the calibration guide at the moment and PID tuning the hot end. Exciting!

The true test will be that first print :)

Much thanks geneb and IMBoring25!

Edit: Oddly enough I can't seem to print yet due to the extruder not allowing itself to drop to printing temperature. Even if I select "shut off all heats" from the printers control screen.

I don't understand what you mean by "drop to printing temperature"...

What's your *exact* process to print a part?

Using MatterControl if I attempt to start a print and the nozzle temperature is above the temperature for the filament in the print operation it remains nearly at its current temperature.

Ex: the LCD and Mattercontrol display a nozzle temp of 227. I start a print via MatterControl and it diplays "waiting for Extruder to Heat to 210." However it never reduces temperature. ( in this case it maintains at 228.3-228.6).
It is worth noting that the displayed starting temperature was 225, which shouldn't be after it was off and had no power.

What does the front panel of the H2 say the nozzle temp is?

When turned on it stated 111, rapidly rose, and has gotten to and fluctuates from 176-178 in varying increments (it did make it up to 190 toward the end of typing this post). This is standalone, with no connection to a computer.

You've got something mis-wired I think. The thermistor should be reading around room temperature - under 30C (unless the room is REALLY warm).

Take care to make sure that the 8 pin connector that goes into the hot end is wired correctly. There's a tiny pin 1 mark on the connector that's just visible in the PDF wiring diagram that JJ made for the dozuki. It could also be that the thermistor leads are shorted against one another - check for that as well.

Comparing to the resource diagram, I believe it's all wired in correctly. Even gave the wires a little tug to make sure they were in. Checked the thermistor solder points in the hot-end board and touched them up a bit. There was no apparent shorting/connection but it did look like a cold solder...it has been a while ;) .

Reconnected the hot-end whip, turned it on and waited. The nozzle temperature displayed was 11 to begin and after 10 minutes or so it was maintaining near 39-40.

Briefly after however, while typing this, the LCD screen displayed "killed" at the bottom. After I noticed this and watched the screen the temperature rose slowly at first and jumped exponentially. I turned it off when I saw it display over 200. One step forward and two steps back

I'm glad you posted the photo of the whip connector. I'm pretty sure you've got it backwards.
See this diagram: https://seemecnc.dozuki.com/Document/23/.pdf

You see how in "Detail C" it's showing you that tiny little arrow at the top? That's pin one. From my (admittedly poor) memory, the access holes on the connector are on the "back" face and the tiny arrow is on the "front" face. Since the access holes are facing the camera, I suspect the connector is on backwards. The problem is that I can't be 100% sure because the image isn't large enough to easily identify the pin one marking (which is only one one face of the connector shell).

(A photo with more contrast showing the arrow)

That was the very same "resource diagram", I poorly described :lol: , that I double checked.

With the thermistor better soldered would it be wise to try and "PID Tune the Hot End" again? The one thing that I wasn't clear on in the guide about this process was how many times I should repeat. Is there a change in values that should be observed or an ideal value range for the Kp, Ki, and Kd?

"Auto-Tuning is an iterative process, so run the routine again via the terminal, sending: M303 P0 S235 X0"

Matterhackers also had a guide for PID tuning that differed slightly, sending: M303 E0 S240 C3, entering the values in Mattercontrols EEPROM setting, and making the value permanent by sending M500. But this was just me searching for more details that might make a mental connection. In this world of programming I am certainly out of my depth and I at least know trying to mix different processes will often yield unsatisfactory results.

Or possibly I am putting the cart before the horse, and should take some time over the week end, or free time and go back through the guide and double check everything hardware related.


...
In some free time however I did take the opportunity to print some pieces for the H2 (on my Robo) and am making it a bit more complete. i.e. not letting the power input, on/ off switch, and LCD screen just dangle( thanks to the files available in the community downloads). Along with a couple of basic top panels and the third, a nameplate :D

Hooray for contrast! ;)

Try this - the connector with the white & green wires are the thermistor leads. Unplug it from the mini-RAMBo and connect a multimeter to the leads and see what resistance you get. It's going to be 100k-ish around room temperature. If you don't get that value, check it again at the PCB on the HE280 where you soldered the thermistor leads to the PCB.

When trying to test the connector with the multimeter probes, are the two metal contacts visible on the opposite side of the connector's clip sufficient for getting the reading? If so I am not getting a reading.

I then checked the soldered leads on the HE280 PCB and also had no reading.

This could be a sign of something that isn't right, or more likely my electronics/circuits ineptitude is showing.

If you're testing at the points where you soldered the thermistor into the HE280's circuit board and you're not getting a reading, either your meter is set wrong (should be the Ohm scale) or your thermistor needs to be replaced.
