Does the stepper for the extruder use 1/16 microstepping too?by pugzor - Delta Machines
Can confirm 100% that there were no jumpers in the kit. Probably why it never occurred to me that I might have to use them haha. All good though. I'm just happy I found something that might explain the strange behaviour. I'm relieved more than anything!by pugzor - Delta Machines
... nope. That could be one of the reasons things are being not great for me. I bet there's more but that'd be a start! Tomorrow I need to get 12 jumpers. I bet it's going to cost me like $1. Such a complicated mistake to have made, haha.by pugzor - Delta Machines
Quotevreihen Quotenkawoah, that's a chair with 3 legs ! It's a DELTA chair!!!!! Nice. QuoteAndyCartJust going back to basics. How many jumpers have you got under the stepper drivers and what type of drivers are they? What's your steps per mm setting for X Y Z in Marlin? I've built about 20 printers now all with RAMPS and 4988 drivers. I've always started with the driver pots centred and neveby pugzor - Delta Machines
I know right! Maybe that's where I'm going wrong... maybe I need a chair with 4 legs? Haven't tuned the steppers (will give that a go next) but I rewired all my stepper plugs that go to the board... was super careful to make sure all the receptacles pop into their sockets nicely... and was rewarded with carbon fibre arms flying around the room! Haha. I bet it is the stepper drivers actually. Yby pugzor - Delta Machines
And now, I shall express my current feelings through the medium of image.by pugzor - Delta Machines
Thanks for the support guys. Yep, I'm going to check my stepper connections again. Some of my earlier crimps were of questionable quality so that could be an issue for sure. Fortunately I got a bucket load of receptacles and housings off eBay so that's not an issue. My X tower stepper did work well though; it was super cool see it run to the end stop and stop on a dime. The Y tower %$#^'d upby pugzor - Delta Machines
I determined that my steppers were wired badly. *sigh* Fixed it. But it still failed. So... uh... anyone want to buy a CP3? Haha.by pugzor - Delta Machines
Sweet mother of mercy that looks magnificent. Once I get bored of my CPIII I'll make the jump to this one. Would be a nice upgrade for a few printed bits and some extrusion.by pugzor - Delta Machines
Woo hoo, more noise and stuff! Unfortunately that's the extent of my success lol. It didn't go for the kill() after I inverted the endstops (thanks Sebastian) however it didn't move a whole lot. I issued a G28 and the motors were kind of jerky and didn't move much... maybe a step up and down? I don't know. Nothing's caught fire yet which is a positive. I'm just not sure on what the next step is..by pugzor - Delta Machines
QuoteAndyCart My understanding is that you can connect to your Arduino from the Arduino IDE using a particular baud rate and COM port and you can successfully upload the firmware? If this is the case then you HAVE to use the same COM port and baud rate for everything else. Have you tried a different USB lead. I know it sounds daft but some work and some don't! Haha, it's not daft, I did do that sby pugzor - Delta Machines
Okay, I've had some success! It's beeping and making noise and doing stuff, and there's comms coming back in Repetier! A very helpful forum member sent me a copy of his configuration.h and it worked first go. So, I highly recommend not using the config.h that's earlier in this thread. .... next issue is that it's killing itself about 3 seconds into calibration hahaha. There's a fairly high whineby pugzor - Delta Machines
Just tried everything again, from start to finish, for COM1, COM3 and COM5, with baud rate of 9600 and 115200 (so six complete attempts with those settings at the Windows level, Arduino IDE level and Repetier/Pronterface/Matter Control level). I've been changing the device name each time as well to make verify that the Arduino IDE write is working, and it's not failing at all. So far device namesby pugzor - Delta Machines
That's a bit concerning then, because I've been able to update the firmware through Arduino IDE several times without issue. Originally windows allocated COM3 but I saw references to 'serial port 1' in the code, so I force changed it to COM1 since it wasn't in use. I might try changing it to COM5 or something when I get home and try that. I've used Repetier, Pronterface and Matter Control all wby pugzor - Delta Machines
Win 8.1 on an Asus laptop. I've made sure it's on COM1 with a baud rate of 115200 (since that's what the config file seems to point to), and have confirmed that these settings are consistent in Arduino IDE and Repetier. I've been playing with it for about 3 hours now, so I'm pretty much ready to sell it already haha.by pugzor - Delta Machines
Just not having any luck. Anyone care to post up a relatively standard version of their CPIII config.h? I might try to start from scratch... something's not right.by pugzor - Delta Machines
Wicked. Glad I checked with the board before I powered it up. Connected it up to D9. Unfortunately it seems I'm having comms problems though. I've been playing with com ports and baud rates but nothing seems to be sticking. I can flash the firmware fine but giving it commands isn't doing anything. It just says "x Command Waiting" where x can be any number of commands I try to give it. Anyway,by pugzor - Delta Machines
So, it appears I've got my CP3 assembled. But there's a problem... I'm finding it difficult to figure out WTF to do with software to drive it, haha. I've managed to get Arduino IDE and load up Rich Cartell's Marlin, as well as your config file AndyCart (I reckon it's going to be a lot closer to mine than what anything else is), but I have no idea on next steps. How do I send it commands to exeby pugzor - Delta Machines
Awesome, thanks for that Andy! Actually just dug up a build plate then (4mm thick mirror, 250mm round, beveled edges) which I hope will be fine. If required I might get something else to adhere to the bottom of it to strengthen it a bit... here's hoping the 4mm is fine though. I'd looked on eBay previously without luck. Might have been looking for glass and not mirror.. who knows. Thanks for tby pugzor - Delta Machines
Mine is nearly together! Just need to install the extrusion module and wire the associated connections. Unfortunately my clumsiness cost me one of my microswitches so that won't happen for a couple of days. Everything else is looking good with only a few hiccups. I still need to find a build plate (I tried cutting glass for the first time... fun but I still need to find a build plate haha). Howby pugzor - Delta Machines
Woo hoo, I picked up my replacement carriages yesterday. That couple of mm makes soooo much difference; they fit perfect on the V slot.by pugzor - Delta Machines
Hey maso, I found that the M3 30mm SHCS held fine and were great for the adjuster screws to clamp the wheels onto the V slot. Obviously I haven't been able to actually clamp onto the V slot yet but it seems great for tapping the thread by itself.by pugzor - Delta Machines
Thanks for that! Looks like I've got a bit of adjusting to do then.by pugzor - Delta Machines
Stray from the BoM, pay the consequences! Haha. Lesson learnt. Out of interest Andy, what settings do you use to generate your carriages? As in, what % fill etc so that you got a good amount of flex for adjustment? Additional question edited in: Did anyone secure the micro switches in with a touch of CA? Yes, I'm clearly a novice at this, just want to stuff as little up as possible. Screwing tby pugzor - Delta Machines
Hey Andy, pretty confident the carriages you sent me were the old design; it'd definitely explain the poor fit for me! I also compared to the sketchup you just posted. In the file, A is ~5.2mm but the piece I've got is ~4.0mm. In the file, B is ~2.4mm but the piece I've got is ~3.3mm. That's all the issue is, I think!by pugzor - Delta Machines
Hmm. Even with the tensioning screw done up fully, there's still around 1-2mm of play between the V slot and one of the wheels (assuming the other wheels are fully in the V slot). That's for me anyway.by pugzor - Delta Machines
Wow, thanks Andy! Without looking at the STLs, what was the modification? How much closer to each other did the wheels move? My guess would have been 3-4mm...by pugzor - Delta Machines
Quotemaso I did find that I had to tighten those carriages down quite a bit. Come to think of it, I had to shave some plastic out of the slot in one of them so that I could get it tight enough. But it really wasn't too bad. And the printer is working swell now. Maybe one of us should try to make a carriage that has the wheels closer together sometime. Honestly, mine are far enough apart that Iby pugzor - Delta Machines
Quotemaso I used OpenBuild V-slot too, and for me it was more than a few mm. I was using 10-32 hardware, so that might affect things a bit. But I couldn't even fit the nut and washer in the slot, much less the plastic part too. I wound up redesigning the t-nuts to fit some small-profile 10-32 nuts. Not the best design, but I superglued each one in and they are pretty sturdy. Edit: Here's the nby pugzor - Delta Machines
QuoteAndyCart That's very possible. They were designed for the Bosch/Rexroth compatible extrusion that I use from KJN in the UK. Fortunately it's only by a mm or two, so it doesn't take too much effort (although my opinion may change by the time I get through all 61 of them haha). Just something for people to be aware of if they're using OpenBuilds V slot!by pugzor - Delta Machines
