You have X=-12 and Y=-6 in your config.h. If your probe is behind the nozzle the Y offset needs to be positive

I've been quiet for a while, but now I'm almost ready to print. I've spent about 10 lunchtimes trying to get my Pi to auto calibrate using various builds of RC's Marlin without much success. Two days ago I decided to give up and try a manual calibration using Andy's instructions. It took about 2 hours to get the bed calibrated and the extruder another 20 minutes. It was quite exciting to finally see the PLA extruding. I just need to add a layer of Kapton tape on the bed and I'll be ready to print my first calibration angle on Monday.

One question: How sensitive is the Pi to being moved. It has to live under my desk most of the time and gets moved out when I want to use it. Will the calibration hold between moves?
Re: Cherry Pi III Is Available
April 17, 2015 05:25PM
I move my Cherry Pi all over the place, from home, to work, to friends. It's very rare I have to adjust anything when I arrive. If I do it's normally a 0.1mm alteration to Z height and that may just be due to temperature changes.
Re: Cherry Pi III Is Available

Help needed for the slightly confused... my printer is now up and running, I have a print of the calibration guide in front of me, and I'm trying to run script 1. All that happens is that the effector zooms down and collides with the bed.

How can I tell it to stop say 10mm higher, so that I have a chance to adjust it down?
Re: Cherry Pi III Is Available
April 18, 2015 11:37AM
Reduce your H value down to 240mm with M666 H240.0 and then increase it from there. Mine ended up at just under 247mm.

Gowen,

I have a slightly different experience with my Cherry Pi, if I sneeze on it I have to calibrate it, but it is a 4XL so I don't know if that makes a difference.
Re: Cherry Pi III Is Available
April 19, 2015 09:46AM
I'm struggling a bit with calibration - I've run scripts 1, 2 and 3 and set the heights nicely; a piece of paper just slips in with a little resistance. However, when I run script 4 the nozzle is 1 or 2 mm from the bed. Nothing much happens when I send M666 R apart from when the number gets too high and script 4 no longer works - also, when I try to run scripts 1-3, the effector moves much too far and the rods go flying... my, don't those rods go a long way! The current value R=125 puts the nozzle in sensible positions for the first 3 scripts, but it's obviously wrong somewhere. I seem to be changing the scale of movement in the X and Y planes without altering Z height in the central position.

So, obviously, something isn't right with my numbers - can anyone comment on what I've got so far?

Altering delta radius with M666 R won't actually move the nozzle closer to the bed. It causes the effector to move in a flat plane from the centre out so it appears to lift the nozzle at the tower bases. You have the correct sequence. Adjust at the tower bases then check the centre. Alter delta radius accordingly then use M666 H to alter Z height to bring the nozzle down so it's correct across the bed. It can take a couple of iterations before it all works out. I normally start out with a 2mm offset on all the towers to give a little 'wiggle' room. If you have built to spec (250mm cross braces and 225mm aluminium tubes) your delta radius should be around 121mm and diagonal rod length around 231mm

I know what you mean. I have some deep gouges in my aluminium bed where the nozzle hit the bed and then ploughed sideways. I had to use some emery cloth to get the burrs off. It's a wonder the nozzle still works; I was half expecting it to be clogged with aluminium. Once I get the kapton tape on it should bridge the grooves.

Is there a decent website that describes the principles of delta motion?

First Print Time

So the day has come. I got the Kapton Tape stuck to the base plate, warmed it up, did a sliding paper test, sliced a calibration angle piece from Thingiverse and started printing.

Then I stopped printing when the first layer wouldn't stick.


So I added a brim, which also wouldn't stick.


Then I changed the first layer thickness which made it worse.


So I reverted back to the previous settings and gave the bed a good clean which worked for a little while.


With the end of lunch fast approaching a grabbed a glue stick and gave the bed a light coat, waited for it to dry and then had one last attempt. It stuck although the first layer wasn't pretty and got through to the end of the print without further issue. With a brim and glue stick it took some effort to remove the part. The final dimensions were within about 0.3mm of the design size which is good enough for me.


I did notice there was some places where it looks like not enough filament was being fed, although when I checked it I was getting about 105mm when asking for 100mm.


Would anyone care to share some screen grabs of their CURA settings for PLA or offer some thoughts on why the first layers wouldn't stick without glue?

Here is the obligatory first print video: [vimeo.com]

Well done Gary. From the pictures it looks like your nozzle is a little high. Try dropping it 0.1mm.

Right. I'll try that tomorrow. What would you recommend for the first layer height and feed, and the subsequent layer height and feed?
Re: Cherry Pi III Is Available
April 22, 2015 01:21AM
I normally use 0.3mm @ 25mm/s as my first layer speed and height and have it slightly 'squished' on the bed. I just use kapton tape wiped with acetone at 60 degrees C as my print surface. Subsequent layer heights are really dependent on the model and your preference. I normally print at 80mm/s, 50mm/s for higher quality prints.

A Little advise if you would

I am having great difficulty getting my 4XL to calibrate and I think it may be to do with my diagonal rods being wrong length.

I have used 450 mm extrusion's for the top and bottom and 1000 mm for the towers this gives me approx 295 mm radius for the carriage runner's which gives a width between towers of approx 510 mm.

Using the online deltabot calculator it suggests arm length of 515 mm which seems a little long to me but I'm willing to try it. using the 80% suggested by you it says around 410 mm should be ok My current ones are 429 mm.

What would you advise

Doug
Re: Cherry Pi III Is Available
April 22, 2015 04:21AM
The proper length for the diagonal rods depends on the delta radius, which depends not only on the distance between the towers but also on how far inboard of the towers the bearings for the top of the diagonal rods are, and the effector radius (how far from the centre the mid-point of a pair of lower bearings is). What is your delta radius? You can estimate it with as ruler: with the effector centred, it is the horizontal distance spanned by a diagonal rod (bearing to bearing).

Thank's Dave

Delta radius is as near as makes no odds 236 mm that is centers of bearing's

is there a set ratio between Delta Radius and Delta arm length?

We will get there soon my current rods are 429 mm but I am starting to suspect that there may be a small variation across the set

Edit after some reading I have found a suggestion that the angle between Bed and Diag Rod should be around 20 degrees at the extreme now with a tower to opposite edge of bed being 495 mm and a carriage offset of approx 30 mm and effector offset of approx 35 mm leave me at 430 mm I calculate that to give me an ideal rod length of 457 mm (430/cos20). If I use the 60 degree rule when homed then that would be 236/cos60 which equal's 472 mm.

Does this make sense and which would be the preferred option ie is longer better in this case.

Re: Cherry Pi III Is Available

I am not an expert in this field, but from a control point of view it is indeed the ratio of diagonal rod length to delta radius that matters; which is equivalent to saying that you should aim for a particular angle when homed. For my Midi Kossel (which is working well), I kept the ratio the same as it was in my Mini Kossel, at 2.05:1. The 60 degree when homed rule gives a ratio of 2:1, so more or less the same.

One disadvantage of longer rods is that they reduce the resonant frequency of the head/rods assembly and make it more prone to vibration.

However, even with your present 429mm rods, you should be able to print over a reasonable part of the bed, avoiding the extremeties.

Thanks for the input good info but it doesn't really help in this case as that is all based on Marlin firmware which I am not using and it looks like my rods are not quite right so I am in the process of making some new ones slightly longer (And make sure they all come out exactly the same length).

Time to cut down my Carbon Fibre tube and fit the Balls to one end (Already have them mounted at one end) Think I will try at 470 mm and see how we go.

Re: Cherry Pi III Is Available

Well, I'm making some progress - or, to be exact, 5 steps forward and 1 or 2 steps back.

I've got X, Y, Z, R and H just about right, and I've started to do some test prints. Unfortunately I'm having trouble with slipping belts, every layer or so a belt will skip a tooth and screw up the print. I've identified one or two issues already:

Motor fixing - if I tighten up the motor fastening screws as much as is necessary to hold them in place then I'm starting to crush the plastic. My frame prints were to spec but my M3 washers have quite a small outside diameter, which means they tend to dig in a bit. I could use over-size washers, but I think I'll fix this with a metal plate on the screw side (I have the necessary materials and technology!).

Motor pulleys - the tooth profile doesn't look as well-defined as on my Prusa's pulleys, so I think I need to find some better ones.

I'm starting to think that I need to put the Arduino/RAMPS boards outside of the frame so that I can get at them easier - I've already had to remove the bed 3 or 4 times today to make some tweaks, and that messes up the calibration. That's not a criticism of the Cherry Pi of course - most deltas have the board inside the frame. Alternatively I may just go for a totally different board that doesn't require regular fiddling - my boards & stepper drivers were China's finest products (ahem) and I'm not hugely impressed - perhaps it's time to go up-market.

But in all other respects - I'm slowly getting there! smiling smiley

Can strongly recommend the DUET dead easy to configure and DC42's Firmware is the Dogs Bollxxxx as they say (I Know I haven't got mine fully dialled in yet but will have soon convinced my Diag Rods are wrong and my frame isn't stable enough Bracing about to go on it as we speak)
