Sovol SV02 IDEX

Sorry to hear that you are having so much trouble with your printer. I think you are on the right track with pay pal. I think that the company is just dancing around the merry-go-round. What ever happeens I hope you get satisfaction!

Apparently, the inexpensive IDEX printers are “not so much”.

I did get a email from them this morning saying that they are on holiday, I was under the impression the Chinese New Year started Feb 1st, the want to send me the hotbed kit but I guess that won’t happen for at least a week. They tried to tell me that the 3D Touch was working as designed. BS it fails 95% of the time. Will make a video pointing out the issue closer. The even replied to the question about Octoprint, said they had to talk to an engineer as they hadn’t heard of that bedore. I checked and in fact the define line is commented out in the code. My just fix that myself and buy another Raspberry Pi

I have to say, I haven’t heard a lot of good things about BL Touch clones.

It’s what came with the SV04, Sovol trying to save a buck I guess. I’m checking with TH3DStudio to see if I can just replace the probe with the EZABL problem solved. I never have issues with it on the E3V2, even a real BLT threw me fit on it too.

It’s weird how you have so much trouble with BLTs while I haven’t. I wonder what the difference is.

You know I wondered that too. Ive done everything I can think of to help. Moving the laptop helped some. I normally play music over bluethooth so I turned that off and didn’t make a difference. The electric panel is in the same room but it’s in a metal box. All the lighting is LED so I’m out of thoughts. It is odd that I have so many issues with BLT’s

You don’t live near Skinwalker Ranch do you? :wink:

No not even close, Im south of Irv. I do live my a radio transmission tower, that I think is a cell tower but don’t know for sure. It doesn’t seem to mess with anything else in the house. I ordered a space blanket to put over it to see it that does anything.

Sorry, the Skinwalker Ranch reference was a joke. I guess you haven’t heard of the TV show. :slight_smile:

LOL actually I hadn’t heard of it, but did look it up.

@Irv_Shapiro could you please change the title of this thread to read SV04. I tried to edit it myself but wasn’t able too. Thanks

If you do a quick search you’ll find it’s this area of NE Utah where really odd things seem to happen. A team is trying to figure out what’s going on, and they’re making a show about it. There’s another ranch, Blind Frog, where some odd things are happening too, but they’re mainly after what they hope will be Aztek treasure in an underwater cave.

Maybe they would want to make a show about my BLTouch oddies

My SV04 was on it’s good behavior most of the day. Printed several 2 color blocks to line up the right extruder with the left one. Printed a prototype part for my Traxxas transmitter. Made a couple of changes in Freecad and sliced the new version. Threw it on the printer and every time it would home I’d get an error. Stop, restart, power off/on the printer several times. The only thing I can think of is the main board got warm and causing this. I’ll try the same file tomorrrow and see what happens. I did have the Ender 3 v2 running next to it but it’s been running most of the day too.

I have faith in you, you will figure out the printer, you are already getting some prints.

Saw a video where someone took a BLTouch apart and cleaned it with electronics cleaner. Nothing ventured nothing gained. so I took the 3DTouch off and removed the pin, sprayed electronic cleaner through the hole and holding the pin with tweezers sprayed it too. Let all this dry then reassembled. Did a bed level and bed mesh without errors so this was a good sign.

If this keeps occuring I think I’m going to replace the 3DTouch with the CR-Touch from Crealiity. From the reviews Ive seen everyone like it. Better built with a metal pin. Luckily the wiring is the same as BLTouch so it’s a drop in replacement.

Is your bed a metal or glass plate? I understand that the CR-Touch does not work well with glass. I would love to have an automatic bed leveling system for the Artist-D. They missed the mark on that. There again, once I took the spacers out of the bed center bolt, once I level the bed, I do not have to re-level until I remove the glass and clean it. Another thing they missed the mark on.
I watched a couple of videos on two other IDEX printers, other than yours and mine, and both have serious problems, just like the evaluations of the Artist-D. The biggest complaints I have seen on the Artist-D was the extruders, and I feel I have solved my problem. Even in IdeaMaker where the default flow is 95% it prints great at that value.
On the note of you cleaning the CR-Touch, I think I would play that out until it gives you more problems.

I took apart the BL Touch that got fried the other day. The yellow tape around the top ‘neck’ is covering copper coils that are used as an electromagnet to pull up the pin. The rest of the inside is basically empty – it’s just a guide for the pin. The main reason I took it apart, though, is to recover the pin, so I have another spare, just in case. You get it out by removing a grub screw in the top of the BL Touch, then the pin can slide out.

I also recently killed a CR Touch. Took it apart. It is built better than the BL Touch. The magnet that pulls the pin up is inside a metal cylinder that’s inside the housing. The pin slides through the metal cylinder:

However, be very careful of the wiring. I fried my CR Touch because, although it would go up and down as expected on power up, it would not trigger the Z axis to stop. I could not figure this out. If the wiring is the same why won’t it work?

I searched for an answer online and found a forum where someone said the wiring differs from the old BL Touch units and they posted ‘correct’ wiring. DO NOT do this! I did it and fried the CR Touch immediately on power up. I don’t if know the person who posted was serious or a troll trying to lure people into frying their hardware.

In any case, I believe the true answer lies in the firmware configuration for the BL Touch. In Klipper this is super easy. In Marlin I guess you’ll have to recompile. Basically, I think it comes down to pull-up resistors.

At least in Klipper, the ! and ^ are used, as in this example:

#[bltouch]
# DO NOT enable touch mode, doesn't work on this clone probe!
#sensor_pin: ^PA2
#control_pin: PA1
#x_offset: -38
#y_offset: -9
#samples: 2
#speed: 1
#sample_retract_dist: 2.0
#lift_speed: 1
#samples_result: average
#samples_tolerance: 0.100
#samples_tolerance_retries: 0

In the line #sensor_pin: ^PA2, the ^ is used to tell Klipper that the probe has a pull-up resistor. Without it, Klipper will not recognize the Z endstop. I don’t know how Marlin specifies pull-up resistors.

The 1st time you go to Autohome I recommend making sure there is plenty of clearance between the nozzle and the bed, tell the printer to Autohome, then trigger the CR Touch with a finger when the printer starts to lower the hotend, all while keeping a finger on the power switch. If the hotend immediately stops lowering, “yippeee”. If not, it’s time to dig into the Marlin documentation and Visual Studio.

Oh, 1 other thing: the wiring connector on the CR touch is on top. The kit comes with a special mounting bracket that has a notch in its side to allow the plug on the cable to reach the connector on the CR Touch.

So far so good, I forgot to check the Z-offset after removing and replacing the 3DTouch so I set the Z-offset and kept my fingers crossed as I did the mesh again. It completed again, think this the 1st time it has done to meshes without a error.

I contacted TH3D about using a EZABL on it and it’s not a direct drop in replacement. EZABL works off the endstop pins where as the BLTouch attacks as a servo. It sounded more complicated that I had hoped. Did indicate that sometime in the future the SV04 would be supported. Guess I’m stuck with the BLT type probes for now.
