* I'm now using a 2:1 mix of PVA glue and water, works fine!
* the residual print warping issue was due to an unlevel print head, caused by the PLA part being warped. NOTE: that the cooling fan on the print head has only one screw and can easily be hinged up causing no airflow over the heatsink. This WILL warp your print head!
* Further to the fan ducts, I believe they are there to help with bridging, so definitely don't remove them
* Fill density helps a lot too. Just a raise from 20% to 30% using star infill made a huge difference to warping and strength
* Also important to get your print speeds dialled in, experiment and watch the print. The slower you go the better the print, unless it's bridging!
* I'm having trouble with adaptive slicing, so switch that off...]]> racitup Fisher Mon, 10 Jul 2023 12:59:36 -0400 https://reprap.org/forum/read.php?409,893089,893098#msg-893098 Re: Unlevel print head https://reprap.org/forum/read.php?409,893089,893098#msg-893098
I printed a new one from PETG which is a bit higher temp than PLA so hopefully will be more robust!]]> racitup Fisher Mon, 10 Jul 2023 12:46:47 -0400 https://reprap.org/forum/read.php?409,893089,893091#msg-893091 Re: Unlevel print head https://reprap.org/forum/read.php?409,893089,893091#msg-893091 dc42 Fisher Sun, 09 Jul 2023 14:52:13 -0400 https://reprap.org/forum/read.php?409,893089,893089#msg-893089 Unlevel print head https://reprap.org/forum/read.php?409,893089,893089#msg-893089
Because of the calibration routines, I can only think that the head itself must no longer be flat, so I will try printing a new one.

On a delta, is there any other way the head could be unlevel? The rods themselves are laser cut so hard to imagine they are out of tolerance, and presumably any differences in them and the carriages would be calibrated out anyway?
I have been through and adjusted all the configuration variables for endstops, home position, etc and always run the mesh grid compensation and delta calibration.

Richard]]> racitup Fisher Sun, 09 Jul 2023 09:34:00 -0400 https://reprap.org/forum/read.php?409,893070,893087#msg-893087 Re: Replacement connecting rods? https://reprap.org/forum/read.php?409,893070,893087#msg-893087 I'm going to try using the existing ball ends and just replace the rods.

For anyone else looking for PETG advice:

* I don't recommend removing the fan ducts, they don't seem to make a difference to the print other than they may prevent/cool plastic that is stuck to the outside of the nozzle meaning it doesn't oxidise and fall off into the print leaving ugly brown streaks
* It's very important to reduce the first layer speed a lot. On very small parts I needed 20%. I probably wouldn't go above 50% at all
* I did eventually get 80degC bed temperature working with a 250degC nozzle temperature. I was using 230degC before and I think the hotter filament compensates for the cooler bed. I read an article saying 250degC is best for PETG in terms of strength. The manufacturer recommended 230degC
* I'm now trying a glue on the bed. It is covered with kapton tape, and on top of that I'm painting on a 50:50 mix of PVA glue and water, that I read works instead of all these expensive glues around. It certainly hasn't made things worse and I think just gives the bed a bit of a matt surface finish that helps. Before that I tried a 600 grit sandpaper on the tape surface which I think probably helped
* I haven't tried the external heater again but am trying to prevent draughts
* Drying the filament certainly hasn't made things worse either
* Good quality filament will help. I inherited a reel of PLA that is awful. It literally has lumps of brown plastic moulded into the filament randomly which would cause a jam and block the nozzle, which obviously doesn't help with print anxiety!
* Obviously getting the print height consistent across the whole bed is vital, so make sure you do the mesh grid compensation and calibration with the nozzle hot. I have a raised spot opposite a tower which I don't really understand

Initial results are promising, and it's not that much harder to print than PLA :)]]> racitup Fisher Fri, 07 Jul 2023 12:49:24 -0400 https://reprap.org/forum/read.php?409,893071,893075#msg-893075 Re: PETG advice https://reprap.org/forum/read.php?409,893071,893075#msg-893075 dc42 Fisher Thu, 06 Jul 2023 01:19:08 -0400 https://reprap.org/forum/read.php?409,893071,893074#msg-893074 Re: PETG advice https://reprap.org/forum/read.php?409,893071,893074#msg-893074
Unfortunately on a Fisher (or at least the one I'm using; an old Duet 0.6) the fan speed doesn't change. I guess it may have been wired up wrong though.

I'm hoping leaving the head ducts off (that direct the airflow directly towards the nozzle) it will have a similar effect to reducing the fan speed and keeping the print hotter for longer]]> racitup Fisher Wed, 05 Jul 2023 21:57:56 -0400 https://reprap.org/forum/read.php?409,893071,893072#msg-893072 Re: PETG advice https://reprap.org/forum/read.php?409,893071,893072#msg-893072 dc42 Fisher Wed, 05 Jul 2023 15:53:14 -0400 https://reprap.org/forum/read.php?409,893071,893071#msg-893071 PETG advice https://reprap.org/forum/read.php?409,893071,893071#msg-893071
Another thing I'd like to do with the Fisher Delta is print with PETG.

I have had a brief try and it went okay, but it didn't completely adhere to the bed at 85degC and warped as a result, so I will try 90degC next.
But the two bad things that happened:
1. The head ducts melted
2. The nozzle got completely blocked

I think this was because I directed a small fan heater at the head to try to increase the ambient temperature so the whole thing overheated.

The things I'm going to try:
* Move the heater a bit further away
* 90degC bed temperature
* Leave the head ducts off
* Dry the filament

Does anyone else have experience of printing PETG on a Fisher Delta and have any advice?
Do you think I have any chance with my approach and without a heated chamber?

Thanks in advance,
Richard]]> racitup Fisher Wed, 05 Jul 2023 14:57:12 -0400 https://reprap.org/forum/read.php?409,893070,893070#msg-893070 Replacement connecting rods? https://reprap.org/forum/read.php?409,893070,893070#msg-893070
First post here and bit of a newb!
I have access to an ageing Fisher Delta and the acrylic head connecting rod ends are warping quite badly, so much that they are becoming loose on the ball caps.

I was wondering if anyone knew/had tried replacing them with metal rods with ball joints? They will obviously be much more robust, accurate and longer lasting.
Something like this with some M4 threaded rod:
[www.amazon.co.uk]

May need to widen the carriages and head to use the bolts the other way around and have the ball joints pressed against the plastic (with a washer).

Thanks in advance!

I'm working with a macbook pro.

I inherited the machine from a friend of my parents. I know the machine is functional as I was given a full demo when I picked it up, but since getting it home I cannot make any sort of link to my laptop, and I can't actually tell if the machine has turned on (I was so excited when I got it that I forgot to listen out for what 'on' sounds like). The fan doesn't turn on and the nozzle doesnt heat up. The power pack is registering power, but am I missing something as simple as a switch on the machine itself?

I would be so, so appreciative if anybody could walk me through in absolute baby steps. I took a lot of notes on everything that happened after start up, but the start up in the demo was so quick and smooth that it didnt seem more complex than connecting all the wires (power, internet, connection to laptop) and opening up reprapfisher. My laptop cannot locate the machine and as I say, I dont think it's even turned on.

Here's to hoping someone here can help me out!

I have managed to commission it ok and can print the robot ok.

I have generally been able to print things ok with a nice finish but im finding that during the print my extruder motor will click occasionally.

What would be the first thing to try? I don't want to just try things randomly if there is a good place to start.

Increase print temp? Reduce print speed? Could the tension be too high on the extruder idler?

I don't seem to get blockages during a print although i have had a lot of problems with the hot end where the PLA gets a buldge in it before the nozzle. My bowden tube is butted up against the nozzle. Its the early one where you screw the bowden tube into it and drill it out manually. No problems with initially feeding the PLA through to the nozzle.

I have ordered a different PLA just in case it is of poor quality but it does seem consistently 1.75mm.

Hot end fan is running during print

All standard settings apart from homing and bed levelling stuff.

PLA at 200C. Glass unheated bed.

Any help would be appreciated.]]> jayuk022002 Fisher Mon, 12 Apr 2021 05:37:21 -0400 https://reprap.org/forum/read.php?409,881505,881505#msg-881505 My printer gives a very bumpy map when I scan it https://reprap.org/forum/read.php?409,881505,881505#msg-881505 phellykz Fisher Sat, 13 Feb 2021 10:49:01 -0500 https://reprap.org/forum/read.php?409,880128,880159#msg-880159 Re: Auto Delta Compensation crashes into Z Tower https://reprap.org/forum/read.php?409,880128,880159#msg-880159 Odd that those files are on the SD card that ships with a Fisher and there isn't a note to delete them in the build instructions.]]> aracdin Fisher Mon, 04 Jan 2021 05:00:10 -0500 https://reprap.org/forum/read.php?409,880128,880137#msg-880137 Re: Auto Delta Compensation crashes into Z Tower https://reprap.org/forum/read.php?409,880128,880137#msg-880137 dc42 Fisher Sun, 03 Jan 2021 16:00:10 -0500 https://reprap.org/forum/read.php?409,880128,880128#msg-880128 Auto Delta Compensation crashes into Z Tower https://reprap.org/forum/read.php?409,880128,880128#msg-880128
I've just built my Fisher and am running through commissioning. I have gone through all the steps up until Bed Probing successfully.
I can move the head in each direction and the correct distances using the web interface.
But, each time I try and execute Auto Delta Compensation, the head crashes into the Z Tower (to the left of the Duet Ethernet/ Power sockets).
The steppers keep driving until I can get to the Emergency Stop - by which time some of the rods have disconnected.

Can anyone point me in the right direction?

Superglue fixed it long enough to print some replacements, as the idler broke on both towers facing the front 8-)
Print now looks a lot better,
[attachment 115698 IMG_20200527_010050.jpg]
Nozzle is too far from the bed near X-Tower and too close between Y and Z, but as I made adjustments to the X-endstop-offset in the last couple of days (to counter my "problem") I guess that reverting this will give me a smooth print. Didn't have time for that yesterday though.
