Fisher heatbed We have put together a heatbed kit for people to upgrade their Fishers, to allow printing in a broader range of materials, such as ABS, HIPS and PETG. You'll need a 120W PSU, which beta owners will already have, but otherwise the bed is a straight replacement for the standard (un-heated) one. Files are on github for those who are interested https://github.com/emaker/Fisher More details on the blog https://emaker.io/news/fisher-delta-heatbed-kit-available/ Let me know if you have any questions. https://reprap.org/forum/read.php?409,669661,669661#msg-669661 Tue, 10 Mar 2026 11:14:25 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?409,669661,723386#msg-723386 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,723386#msg-723386

Update on heatbed: I've been using it regularly to print ABS and it's been faultless. Kaptop tape on the metal and a small amount of ABS Juice wiped over with a tissue makes the prints stick every time.

Very pleased with it. I think I'll give up on PLA!

One question: could I run the printer without the fan on? I notice M107 Gcode has no effect, so I'm thinking of just unplugging it. Will it be OK? At the moment the fan ducts are shaped in a way that tape wont stick easily.

Out of interest what retraction sand speed settings are you using. I'm finding the 80mm print and 50mm retraction is causing a lot of filament stripping. Doing some test prints with low retraction and so far no stripping but quality is poor.]]> DADIY Fisher Tue, 15 Nov 2016 16:04:03 -0500 https://reprap.org/forum/read.php?409,669661,723333#msg-723333 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,723333#msg-723333

Glass frame clip otherwise known as emo clips.]]> DADIY Fisher Mon, 14 Nov 2016 10:31:26 -0500 https://reprap.org/forum/read.php?409,669661,723001#msg-723001 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,723001#msg-723001 Recently purchased 3mm float glass for the Fisher to place on top of the heatbed. I need to fasten the glass to stop it moving when printing but I would rather not use using glues etc. The issue which I sure you are all aware of is that there is minimal space to apply bulldog or similar clips.
Does anyone have any suggestions as to what clips I can use, I tried printing some with PLA but the are very brittle and break easily.
Your help is much appreciated.]]> Gary J Fisher Mon, 14 Nov 2016 08:51:03 -0500 https://reprap.org/forum/read.php?409,669661,715648#msg-715648 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,715648#msg-715648
I've made a slight modification to mine and added an EC3 connector and RC servo connector to the wires of the heatbed. This is in case I want to fully remove the bed to remove intricate prints or clean the bed or maybe go back to non-heat bed.

I printed my first 20x20mm cube in ABS this morning and am very impressed it worked first time!

The sd card I was using became corrupted and I reformatted to remove issues. After re-loading the Firmware and other folders onto the card, amending the config g file to ensure correct height of the nozzle from the heatbed and other settings I re-inserted the sd card into the fisher. Unfortunately it no longer picks up the heatbed on the DWC Panel. I added the command M305 P2 R4700 to thermistor category under the previous M305 command for the nozzle but the heatbed is still not showing on the DWC Panel. Thanks in anticipation.

Sounds like you may still have a M140 H-1 command in your config.g file. If so, remove it or comment it out.]]> dc42 Fisher Mon, 17 Oct 2016 15:33:48 -0400 https://reprap.org/forum/read.php?409,669661,714765#msg-714765 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,714765#msg-714765 Gary J Fisher Mon, 17 Oct 2016 15:08:36 -0400 https://reprap.org/forum/read.php?409,669661,714706#msg-714706 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,714706#msg-714706 AndyKay Fisher Mon, 17 Oct 2016 12:21:38 -0400 https://reprap.org/forum/read.php?409,669661,705065#msg-705065 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,705065#msg-705065 Steve]]> stevebeale Fisher Sun, 04 Sep 2016 09:10:52 -0400 https://reprap.org/forum/read.php?409,669661,705054#msg-705054 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,705054#msg-705054
The homed height in config.heatbed.g was set a little high. It has now been reduced to 161mm and updated on github. See the M665 command to adjust.

I tried with my worst filament, a red PLA from Prima3D
After some tests with Kapton tape,there was no grip at all.
I installed the BuildTak, bed at 70 and filament 200, the filament is sticking well.

I can finally finish my spool with other things than failed parts!

Here is an example : a reworked part to replace the acrylic arm from the extruder.

[attachment 81396 IMG_0565.jpg]

This kind of part with small footprint was impossible before

I enjoy it]]> Greg_be Fisher Sat, 16 Jul 2016 14:15:46 -0400 https://reprap.org/forum/read.php?409,669661,678111#msg-678111 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,678111#msg-678111
This addition makes the heatbed completely removable and will ease replacing Kapton and carrying out other maintenance on the Fisher. This arrangement has little chance of becoming accidentally disconected as the JST plugs and sockets are quite firm once fully engaged. If you have not used JST connectors before, I suggest you purchase a crimping tool, rather than try to solder the JST plug's contacts. Works a treat!]]> SSMagic Fisher Sat, 25 Jun 2016 16:15:38 -0400 https://reprap.org/forum/read.php?409,669661,673798#msg-673798 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,673798#msg-673798
If you don't want the airflow across the top of your part from the nozzle ducts, you can easily remove them. There'll still be a downdraft over the part, but it won't be so aggressive. That's what I do when printing with ABS, as otherwise it tends to delaminate during printing.]]> jmgiacalone Fisher Sun, 12 Jun 2016 18:13:36 -0400 https://reprap.org/forum/read.php?409,669661,673789#msg-673789 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,673789#msg-673789 jmg123 Fisher Sun, 12 Jun 2016 17:44:19 -0400 https://reprap.org/forum/read.php?409,669661,673744#msg-673744 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,673744#msg-673744

You may need a power supply which can provide more current than the one you linked to.
Cartridge heater resistance is 6 Ohms and the bed is 3 Ohms. So at 24v, the hot end will draw 4A and the bed 8A. Your power supply therefore needs to be able to supply at least 12A at 24v, or 288W power. These figures cater for powering all the heaters at full power, which is not necessary except to speed up the warmup time from cold. During printing, the heaters operate at a fraction of their maximum power.

It think it should be ok, the e3dV6 30w Cartridge on my hotend is 24Volts/19.2Ohms = 1.25Amps . The PSU has a function where you can internally chain both channels together in series or parallel for 60v/5A or 30v/10A, so allowing for the overhead of the duet itself (~150mA) and the 4 steppers (500mA Each) means that it should be able to feed the bed around 6.6A = ~ 158W ~ 83% of the intended power whilst running everything flat out, or more if the motors aren't doing anything during initial bed warmup phase. I always run it with the over current and over voltage protection enabled, so if it cuts out, I can just back the bed power down a fraction until it is happy.]]> jmg123 Fisher Fri, 03 Jun 2016 11:41:07 -0400 https://reprap.org/forum/read.php?409,669661,670588#msg-670588 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,670588#msg-670588 Thanks for your order!

You can adjust the M301 S parameter to reduce the power available for the heaters, but with only 5A available, I fear you may need to reduce the power so much that your heaters will not be of much use.]]> jmgiacalone Fisher Fri, 03 Jun 2016 06:18:34 -0400 https://reprap.org/forum/read.php?409,669661,670576#msg-670576 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,670576#msg-670576 I can not wait to test it !]]> Greg_be Fisher Fri, 03 Jun 2016 05:42:04 -0400 https://reprap.org/forum/read.php?409,669661,670234#msg-670234 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,670234#msg-670234

Hello jmg123,

I've been planning to test the Fisher with 24v, and in fact received a suitable power supply in the post today, so I'll let you know how it goes.

We do have bed springs. I'll get them listed on the site over the next couple of days.

Great thanks, I've converted my fisher to 24V and be powered by one of these so I can also easily try it at 19V and 24V, just wanted to check, that the 24V was theoretically possible before I gave it a go.]]> jmg123 Fisher Thu, 02 Jun 2016 05:15:41 -0400 https://reprap.org/forum/read.php?409,669661,670149#msg-670149 Re: Fisher heatbed https://reprap.org/forum/read.php?409,669661,670149#msg-670149 bgkdavis Fisher Wed, 01 Jun 2016 20:38:04 -0400
