Re: z height

To my knowledge, you shouldn't run the calibration process through the Calibration Menu on the LCD. Apparently it causes some odd behaviors. (This may be one of them, I do not know from experience, but I have read multiple times that you are not to run the G29 script in this fashion.)The correct wa...

Re: G29 issues after conversion to HE280

It could be that the accelerometer is not working correctly. To figure that out use the G-Code terminal of Mattercontrol. Send a M261. The return values will be data about the accelerometer. Pay attention to the INT value. Then thump (flick) the hot end with your finger. Send M261 again. The INT val...

Re: A great print remover

This does ot scratch for me because of the angle you use it. Because the way the handle holds the blade the angle it is to the surface is very small. It is almost parallel to the surface so that it does not dig in. That is why this one is so good compared to what I use to do which was try to hold th...

Re: Different auto calibration?

From the code I can find there is no difference. The command from the LCD ends up sending A G29 to the gcode processor.

A great print remover

I have found a great 3D print removal tool that helps remove prints stuck to the bed. Probably does not work on tapped beds. I use it on my PEI bed.

This is a handle for a single edge razor blade. I find it much better than the paint knife that came with the kit.

Re: Accelerometer is not working

In the instruction guide:
http://seemecnc.dozuki.com/Guide/Rostoc ... de/49#s402

Step 12: Labeling the thermistor wires.
Step 22: Determine Thermister lead polaraity

Then later you will use those labeled wires. That is what I was talking about.

If you did that correctly then I'm out of ideas.

Re: Accelerometer is not working

The thermister itself does not care about the polarity however the int line that shares the thermister wireing does. So it must by wired as specified in the instructions. Make sure you did it the way the instructions said.

Re: he280 temp issue

I had this issue when I upgraded my V2 with the HE280 hot end and the old ATX supply. It would not warm up enough to start printing and just hovered under what the printer expected in order to start. This only happened when my room got cooler and I was trying to print at 230 deg for ABS. Around 200 ...

Re: Accelerometer is not working

I don't think any of G29 or callibration or probe code in the standard build applies to the E3D hot end the code is for the HE280 hot end.

Re: Problems with HE280 installation on Max V2

That's great. Glad you finally figured it out. I don't know why except that the accelerometer must not get the desired acceleration from that combination of build plate. That value is configurable in the configuration.h file I think. You could play around with it. It might also be in the EEPROM sett...

Re: Problems with HE280 installation on Max V2

So it looks like the accererometer is working so it probably is not a problem. Other than Max Z height I running out of the usual causes. Default Max Z height on a normal V2 is 360 I think.

Re: Problems with HE280 installation on Max V2

Dale, My current EEPROM reads x1 -123.565 (note the negative vs positive in x2... is this indicative of reversed wires?) No that is the correct value. The left edge of the build plate is in the negative direction. The back edge of the plate by the Z tower is positive Y direction. So that all looks ...

Re: Problems with HE280 installation on Max V2

Ok, then it is most likely the accelerometer may not be working right. You can use the g-code terminal and M261 command to diagnose it. Look for the int pin message and see if change from high to low. First use the m261 command and look at the value of int pin. Then thump the hot end with your finge...

It is a common issue on this forum. It should not happen and is a sign that something is wrong. First thing may be that your belts are not tight. It could also be the that connector to the hot end is partially loose. That causes the accelerometer probe to fail every so often so that the machine does...

Re: Problems with HE280 installation on Max V2

That looks like the printer is going too far toward the X tower and goes off the edge of the build plate. Where probes should go is set by the EEProm values: Z-Probe X1,X2,X3 and Z-Probe Y1,Y2,Y3. They are specified in the configuration.h. But if you did not clear the EEPROM before uploading the new...

Re: Can't get level first layer/Convex bed

If the bed is Convex and symmetric about the middle then adjusting the Horizontal radius will compensate and make it be flat to the hot end.

Re: Cracking noises from stepper motors

If you can move the carriage manually with power off easily then there probably is no issue with bearings or something being too tight.

Maybe it is lack of power or intermittent power to the steppers or rambo board.

That sure sounds like belt slippage to me. The stepper gear is rotating but the belt is not moving and the stepper then makes that sound as it steps past the belt tooth.

Re: Nozzle is high when printing after calibrating Z=0 at papers width...

Yes you can set the Max Z height in EEPROM yourself and then print. That is what I do. However it may be better to set the probe height value instead to compensate. Then whenever you calibrate you may not need to go change the Max Z height.
