Any Azteeg X5 owners, a little help please.

[626Pilot]

Thanks! That works perfectly.

Today I'll work on getting the Z probe set up, and then refine the X5 mount. Hopefully I can have the mount published on Thingiverse soon. I want to design it so you can use the caphead screws and plastic bushings from the RAMBo. (The bushings are because it needs to be stood off, due to the screws holding the board to the mount.) You'll still need four M3 screws and nylock nuts.

Once this is all set up, I'd like to do a thread in the Rostock forum about upgrading to the X5 Mini. If the Z probe works for me as well as it has for the other guy, I think we can finally declare the fix for weird Z=0 behavior.

The firmware is a little raw... understandable, as it's still new... for example, it doesn't report the hot end duty cycle to Repetier, which is a problem for me. However, the way it manages the fan automatically by hot end temperature is a real winner. And unlike my RAMBo, it doesn't just randomly decide to stop responding to extrude requests.

I reorganized the config file to make it easier to get at commonly changed values. (Also, with the extruder step direction inverted - this is necessary for some reason.) I will post it after I have the Z probe stuff figured out.

[Polygonhell]

The dir pins might well have to be inverted, I just found the pairs, wired them up and flipped the dir pins as necessary, they probably don't match the wiring on your RostockMax.
Almost all of of the delta settings can be written automatically to an override file, but PID values must be updated in the config file after you run M303, you also have to specify the extruder when you run M303.

[626Pilot]

The X/Y/Z directions don't have to be inverted, but the extruder does. What's an override file and how do I use it? Also, I notice I have to fully power cycle the board to get it to reread the config - even if I sync and unmount, the reset button isn't enough. Is that normal?

[Polygonhell]

Reset works for me.
The override file is created by one of the M Codes, there is a list on the smoothie site.

Alright, I got the Z probe working. I had to modify the mount to work with my under-slung E3D, which I've uploaded to Thingiverse.

To put it simply, the calibration sucks! It digs in near X and raises something like 0.3mm near Y. There is no setting for me to tell Smoothieware what the offset to the probe is, so it helplessly assumes that the probe is at the extruder nozzle. In reality, the probe is about 50mm away, so its assumptions are WAAAAAY off.

Not sure what to do about this except weep for a little while. However, I should be able to publish the mount soon. I can get decent performance at 0.2mm layer height if I don't go too far from the center. I posted a thread about it here: http://smoothieware.org/forum/t-920408/ ... t-settings" onclick="window.open(this.href);return false;

[Polygonhell]

The offset shouldn't matter a huge amount for the radius calibration, it will unfortunately matter for the endstop calibration, though again I believe it does gradient decent and these should converge.
My offsets more like 20mm, so I don't see much error.
The radius calibration is just doing simple gradient decent, for all it matters it could just measure any two points as long as one is guaranteed to be nearer the center than the other. In fact thinking about it measuring all 4 might actually make it worse because crossing the center point win the probe introduces at least one false minima and one bad measurement could make the chances of convergence much worse.

[626Pilot]

If anyone needs a working config for a Rostock MAX, here's mine. There are some settings under zprobe.* that won't take effect in the stock firmware (only my test branch cares about them) but they shouldn't interfere with anything. The geometry is set to use the new carriage horizontal offset suggested by SeeMe (37.5 instead of 35).

I spoke about doing an Azteeg X5 mount earlier, and it's all finished. Should work with the same screws that came for mounting the RAMBo. For securing the board to the mount, I used flat-headed #6-32s because they fit perfectly into the countersunk holes. Enjoy!

Does anyone know why the X5s take so long to boot? I have to wait about 20 seconds every time I reset it before I can connect.

Does anyone know why the X5s take so long to boot? I have to wait about 20 seconds every time I reset it before I can connect.

If I had to guess, it probably has to do with the bootloader having to initialize the SDCard to load the firmware. I assume it checks the SDCard copy of the code against the copy in it's internal Flash. But that probably shouldn't take anything like 20s. It's hard to know without going through the code, some hardware requires significant delays when initializing, and if smoothie supports optional hardware, it might have to wait on timeouts to see if it's present.

Just out of curiosity, has anyone mounted a PT100 to their x5, or should i go back to the stock sensor if i go with the x5?
